works with -g -O1 -fPIC, fails with -g -O2 -fPIC

[Launchpad Janitor (janitor)]

This bug was fixed in the package fftw3 - 3.2.2-1ubuntu2

---------------
fftw3 (3.2.2-1ubuntu2) oneiric; urgency=low

  * Work around FTBFS on armel, build some files with -O1. LP: #841437.

[Michael Hope (michaelh1)]

Thank you for the bug report. I can't reproduce this with gcc-linaro-4.6-2011.08 on Natty:

michaelh@ursa2:~/linaro/bugs$ /tools/toolchains/arch/armv7l/gcc-linaro-4.6-2011.08-armv7l-natty-cbuild162-ursa1-cortexa9r1/bin/gcc -g -O2 -fPIC -std=gnu99 -c r2cf_64.i

I've tried to reproduce the fault with and without the following options:
 * With and without -fstack-protector
 * With -mfpu=vfpv3-d16 vs -mfpu=neon
 * With and without -g
 * At -O1, -O2, -O3

Fortify shouldn't matter as this is preprocessed source.

I've also tried with:
 * gcc-4.5.3
 * gcc-4.6.1
 * gcc-4.7~svn178624
 * gcc-csl-2011.03-42
 * gcc-linaro-4.5-2011.08
 * gcc-linaro-4.6-2011.08
 * binutils_2.21.53.20110810-0ubuntu2 from oneiric

Could you investigate further please?

[Matthias Klose (doko)]

did you check with -fPIC?

[Michael Hope (michaelh1)]

Yip, the command line is listed in the comment:

michaelh@ursa2:~/linaro/bugs$ /tools/toolchains/arch/armv7l/gcc-linaro-4.6-2011.08-armv7l-natty-cbuild162-ursa1-cortexa9r1/bin/gcc -g -O2 -fPIC -std=gnu99 -c r2cf_64.i

It includes -g, -O2, and -fPIC.

won't fix in oneiric
