Description Adrian Rutledge 2004-06-10 04:12:13 UTC

When emerging XFree86, xcursorgen segfaults when using gcc-3.3.2-r7 when compiled with -O2.

Reproducible: Always
Steps to Reproduce:
1. Emerge libpng with -O2 in the CFLAGS
2. Attempt to emerge xfree
3. Wait long enough for xcursorgen to be used
Actual Results:  
Segfault on the commandline:
LD_LIBRARY_PATH=../../../exports/lib ../../../exports/bin/xcursorgen ...
in directory redglass

Happened to me on PPC32 after upgrading to gcc 3.3.3

The problem is with setjmp, rebuilding linpng with the same compiler as xorg (and htmldoc and other apps using png with setjmp fixed the problem).
