ppl ftbfs in precise on powerpc

[Matthias Klose]

the build fails as shown in
https://launchpad.net/ubuntu/+source/ppl/0.11.2-6ubuntu2/+build/3203034

it is a test suite failure, so the failure could be worked around by disabling the testsuite on powerpc. however ppl is a build dependency of gcc itself.

the build on Debian unstable does succeed

this looks like a regression in memory use, the cc1plus apparenty needs more than ~3.5GB. works with fsf gcc-4.6 and Linaro gcc-4.5.

I have run the test on ARM on a number of toolchains, and confirmed that there is no failure in that case.
The note:
"note: variable tracking size limit exceeded with -fvar-tracking-assignments, retrying without" is present but does not lead to the memory error.

Michael will now help out in reproducing on PowerPC.

This bug was fixed in the package ppl - 0.11.2-6ubuntu3

---------------
ppl (0.11.2-6ubuntu3) precise; urgency=low

  * Build the test suite with -gstabs rather than -g on powerpc, to avoid
    running out of memory (LP: #941676).

Unable to reproduce with linaro 4.8 or 4.9 targeting arm and powerpc.

The Precise Pangolin has reached end of life, so this bug will not be fixed for that release
