Bug 356093 – sys-devel/gcc-4.3.4: tests fail

• Product: Gentoo Linux
• Status: RESOLVED WORKSFORME

[Description mehrunes 2011-02-22 16:58:12 UTC]

Many tests fail when emerging sys-devel/gcc-4.3.4

	=== gcc Summary ===

# of expected passes		49967
# of unexpected failures	101
# of expected failures		169
# of untested testcases		35
# of unsupported tests		385



Reproducible: Didn't try

Steps to Reproduce:
1. FEATURES=test emerge =sys-devel/gcc-4.3.4
2.
3.

Actual Results:  
emerge successful, lots of tests failed

Expected Results:  
tests succeed

No, I'm not aiming to find and report as many bugs as possible. Rather I want to build some python/math/number theoretic packages such as sage, and nothing seems to work.

Is any fresh gcc broken? If yes then which version is less broken? Which version should I use?

emerge --info follows

Please use "sane" C{XX}FLAGS. If the tests still fail after you rebuild your system with sane flags, add a new comment to the bug.

CFLAGS=CXXFLAGS='-O3 -march=native -pipe'

automagically became 

[32;01m*[0m CFLAGS="-march=native -pipe -O2"
[32;01m*[0m CXXFLAGS="-march=native -pipe -O2"
 
And guess what?

gcc Summary unchanged (of unexpected failures	101). Would you like emerge log?

@toolchain:

your call.

sorry, not interested.  especially for older compilers.
