Bug 267367 – dev-scheme/guile fails to complile with CFLAG -O3

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Jens Meißner 2009-04-24 17:56:14 UTC]

dev-scheme/guile fails to complile if CFLAGS is set to "-O3 -mcpu=7450 -maltivec -mabi=altivec -fno-strict-aliasing -pipe". If I run
# CFLAGS="-O2 -mcpu=7450 -maltivec -mabi=altivec -fno-strict-aliasing -pipe" emerge -1 dev-scheme/guile compile fails not.
I remember that it was possible, to disable -O3 in ebuild.

Reproducible: Always

Steps to Reproduce:
set CFLAGS="-O2 -mcpu=7450 -maltivec -mabi=altivec -fno-strict-aliasing -pipe" and emerge dev-scheme/guile
Actual Results:  
compile fails

Expected Results:  
compile should not fail.

[Comment 2 Marijn Schouten (RETIRED) 2009-04-27 10:47:59 UTC]

Please try with guile-1.8.6

[Comment 3 Dmitry Dzhus 2009-04-27 13:55:33 UTC]

Compiles like charm with -O3 and guile-1.8.6.

[Comment 4 Jens Meißner 2009-04-27 16:31:40 UTC]

I can compile guile-1.8.6 with -O3 on i686, ppc and ppc64 without errors.
By the way guile-1.8.5-r1 fails to compile only on ppc and ppc64, but not on i686.

[Comment 5 Mounir Lamouri (volkmar) (RETIRED) 2010-03-08 22:47:38 UTC]

dev-scheme/guile-1.8.6 is now stable for ppc/ppc64. It is fixing this bug.
