gsl self-test fails under gcc-4.4.4-r2

switching to gcc-4.4.4-r2 solves the problem

Reproducible: Always

Steps to Reproduce:
1. FEATURES=test CFLAGS="-march=k8 -mfpmath=sse,387 -O3" emerge =sci-libs/gsl-1.14
 - failure with gcc-4.4.4-r2

2. switch to gcc-4.1.2 and repeat the above: success



Actual Results:  
test fails with gcc-4.4.4-r2

Expected Results:  
successfule emerge for all versions of gcc

I cannot reproduce that with your settings on my box. Could you try CFLAGS="-O2 -pipe"?

The patch to ebuild does not completely solve the problem


   [[ $(gcc-major-version)$(gcc-minor-version) -eq 44 ]] \
       && filter-mfpmath sse


1) As I mentioned is post no. 3, gcc-4.4.3-r2 is buggy too

2) For gcc-4.4.4* and probably other versions of gcc, equivalent to '-mfpmath=sse,387' is '-mfpmath=both'. I doubt that 'filter-mfpmath sse' removes this equivalent form

I reopen the bug

I tested gsl-1.14-r1 ebuild with CFLAGS='... -mfpmath=both ...' on intel processor

result: failure. Error message slightly different:
