Bug 417119 – sys-devel/gcc 4.6.x/4.7.0 - ?

• Product: Gentoo Linux
• Status: RESOLVED NEEDINFO

[Description 404 Error 2012-05-22 15:53:37 UTC]

Using GCC 4.4.x series, GCC can be compiled without any troubles. As soon as the current version is switched to 4.7.x with gcc-config, the compiler fails to be bootstrapped with an Internal Compiler Error (ICE):

/var/tmp/portage/sys-devel/gcc-4.7.0/work/gcc-4.7.0/gcc/alias.c: In function ‘rtx_def* find_base_value(rtx)’:
/var/tmp/portage/sys-devel/gcc-4.7.0/work/gcc-4.7.0/gcc/alias.c:1170:1: internal compiler error: Segmentation fault

Reproducible: Always

Steps to Reproduce:
Emerge gcc 4.6.x/4.7.0 when GCC 4.6.x or 4.7.0 is the current system compiler.



Same issue with GCC 4.6 series: ICE when GCC 4.6.x is bootstrapped
