Bug 70627 – [ttmkfdir-3.0.9-r2] seg fault because of CLAGS

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Joerg Schaible 2004-11-09 19:24:50 UTC]

font dir generation failed on my system for some font directries since ttmkfdir always created a segfault (emerging xorg or starting xfs). Even calling 

ttmkfdir -h

to get the usage just results in a seg fault. After some investigation I found the culprit to be the -foptimize-sibling-calls flag. Without this one, the font.scale generation went fine.

Please note, that the current ebuild already filters the -Ox flags, but this is not enough. If the flag is explicitly set, it must be filtered explicitly!

Somewhat related to 55383, but that one identifies another critical flag, that is not yet filtered.


Reproducible: Always
Steps to Reproduce:
1. CFLAGS=-foptimize-sibling-calls emerge ttmkfdir
2. ttmkfdir -h


Actual Results:  
segmentation fault 

Expected Results:  
print usage line

We only accept bugs with standard accepted safe use flags which are -OX -gX -march -mtune -mcpu and -m32 on x86
