Well, pkg_mkIndex actually attempts to load and initialize the
package, so it's not clear at this point if the problem is in tcl or
in the initialization code of tclcurl. I think we may need to call in
an hppa expert here.

A very similar bug, possibly the same one, appears to be biting the postinst
of gpsmanship, causing it to fail to install. From the build log for xastir
(http://buildd.debian.org/fetch.php?&pkg=xastir&ver=1.6.0-2&arch=hppa&stamp=1129791638&file=log&as=raw)
we see:

Setting up gpsmanshp (1.2-2) ...

ec$
      3481 Segmentation fault | tclsh$TCLVERSION 2>&1 >/dev/null
dpkg: error processing gpsmanshp (--configure):
 subprocess post-installation script returned error exit status 139

It's also possible that this segfaulting is due to a kernel misconfiguration
on the hppa buildd, as the recently-solved Qt FTBFS was. Ask on the hppa
list.

Definitely not a tclcurl bug.

This is also definitely not a kernel config error. paer's kernel throws
SIGBUSes on unaligned memory access, it doesn't randomly throw segfaults.

Subject: tcl8.4: tclcurl FTBFS because tclsh SEGVs on hppa

Package: tcl8.4
Version: 8.4.11-1
Severity: important

hi,

  please have a look at the build log on hppa of the latest upload
of tclcurl 0.14.1-1 package [0]. it looks like tclsh8.4 chokes on the
following 1liner script:

  pkg_mkIndex . libTclCurl0.14.1.so tclcurl.tcl \; exit;

regards
domenico

Only affects hppa, downgrading

IOW, this was fixed in tcl8.4, either by way of fixes upstream (8.4.12-1), or
recompilation with different toolchain (8.4.12-1 or 8.4.11-1.1); the latter
seems a bit odd, though, given that 8.4.11-1 was also compiled using gcc
4.0.1, but for some reason pulls in gcc-3.3-base.

Also note that tclcurl has built on hppa several times since this, including
the very same version (and the only reasonable changes I can see are 2.4 vs.
2.6 kernels and newer binutils). I'm closing this one.
