System: Linux pc61 2.4.17 #1 Mon Jan 28 12:18:28 MET 2002 i686 unknown
Architecture: i686


host: i686-pc-linux-gnu

>Description:
When compiling libsupc++ with -O2 -g1 or with -O -g1, an ICE is triggered by eh_personality.cc:485

>How-To-Repeat:
In gcc-3.1.1/i686-pc-linux-gnu/libstdc++-v3/libsupc++/Makefile, set
CONFIG_CXXFLAGS = -ffunction-sections -fdata-sections -g1
>Fix:
Use -g0
