Bug Description

While installing MySQL 5.5.6-rc on Maverick, mysqld crashed immediately, dumping the following (among other stuff) into its error log:

mysqld: ../sysdeps/unix/sysv/linux/getpagesize.c:32: __getpagesize: Assertion `_rtld_global_ro._dl_pagesize != 0' failed.

It's an upstream issue, documented here:

It looks like it was fixed in Fedora:;a=commitdiff;h=26f25ed8b41240e0268e2e4472a4dc4564ffe146

Any idea if this patch will be coming to Ubuntu?

Here's how I'm compiling MySQL.

I believe this is a duplicate of #647527, although I am not sure.

I get the same issue with statically compiled haskell programs using ghc in Maverick.

(bug #647527 is indeed an earlier report of this issue, but I merged it into this bug because there is more information here.)

The testcase in bug #647527 is at
gcc -O0 -o foo foo.c && ./foo
=> works
gcc -static -O0 -o foo foo.c && ./foo
=> segvs

Fedora applied a workaround, not a fix, which is also what's mentioned to work in the upstream bug:

The patch from Gentoo seems to fix the first issue cleanly, but the upstream report mentions that it doesn't work for iconv.

The Fedora patch looks more like a workaround than a proper patch (since it just disables that piece of code), but the #else branch in;a=blob;f=sysdeps/unix/sysv/linux/getpagesize.c;h=fe9bc8ead727dba829379a71ab9b6a8258822bc4;hb=26f25ed8b41240e0268e2e4472a4dc4564ffe146 looks sensible enough, so please go ahead and upload.

Accepted eglibc into maverick-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See for documentation how to enable and use -proposed. Thank you in advance!

Thanks! I tested it and it works. My test was similar to comment #4.

We don't want to close this bug in natty with the workaround though, as it's only a workaround

eglibc (2.12.1-0ubuntu11) natty; urgency=low

  * Update to the eglibc 2.12 branch (r12365).
    - Fix alignment of AVX safe area on x86_64, issue #12113. LP: #662511.
    - Fix issue #12159, x86-64 strchr propagation of search byte into all bytes
      of SSE register. (LP: #615953)
    - any/cvs-audit-suid.diff, any/cvs-getlogin_r-error-handling-1.patch,
      any/cvs-getlogin_r-error-handling-2.patch, any/cvs-issue12092.diff,
      any/cvs-getlogin_r-error-handling-3.patch, any/cvs-issue12113.diff,
      any/cvs-issue11968.diff: Remove, merged upstream.
    - any/cvs-dst-expansion-fix.diff, any/submitted-etc-resolv.conf.diff,
      locale/locale-print-LANGUAGE.diff: Updated.

  * Sort changelog entries with bzr-builddeb's merge_changelog to help merging
    with Debian; update Debian changelog entries to their latest version, and
    drop Debian changelog entries which aren't in the unstable changelog; this
    keeps the diff between Debian unstable's changelog and Ubuntu's changelog
    minimal (only Ubuntu entries) and makes it easier to review new Debian
  * Copy binutils [mips mipsel] build-dep to minimize delta with Debian's
  * Drop Vcs-Bzr; this package is now maintained in lp:ubuntu/eglibc.
  * Drop version in texinfo build-dep; this is satisfied even in dapper.
  * Move belocs-locales-bin conflicts around to lower the diff with Debian's
  * Copy Debian's libc6-dev-i386 Conflicts with libc6-i386 (<= 2.9-18) for
    some older upgrades; this seems to apply to Ubuntu as well, and reduces
    the delta with Debian just a bit. libc6-dev-i386 is not a commonly
    installed package, and this is satisfied in lucid and later anyway, so it
    shouldn't make upgrades harder, except if people use backports.
  * Drop debian/, libc0.3, libc6, and libc6.1 (these are
    automatically generated) after confirming that generating them results in
    the same data.
  * Drop debian/; ChangeLog* is already listed in
  * Drop debian/ as it only helps powerpc
    upgrades from dapper versions which aren't supported on powerpc anymore.
  * debian/ drop inconsistent quotes around 2.12.
  * debian/local/manpages/gencat.1, iconvconfig.8, mtrace.1: revert differing
    RCS timestamps.
  * debian/patches/series: drop reference to changelog version with respect to
    local-ipv6-lookup.diff as the reference is bogus.
  * Drop debian/patches/alpha/submitted-getsysstats.diff,
    submitted-includes.diff, submitted-lowlevellock.diff,
    submitted-procfs_h.diff; these should have been dropped in earlier merges
    as they are not applied anymore and were dropped from Debian.
  * Drop commented-out hppa/* lines from patches/series to be consistent with
    how other arches were handled.
  * debian/sysdeps/ symlink ld-linux with the same rune as Debian.
  * Drop changes to debian/sysdeps/; Ubuntu doesn't build for Hurd.
  * Remove debian/wrapper/objcopy; was dropped in Debian already...
