Hi, I am using gcc-go 4.8.2 on FC19, 32bit. When compiling even a simple program I sometimes get a segfault, which goes away at the time I remove the optimizations: in ?? () from /lib/libgo.so.4 #1 0xb7459b3d in backtrace_dwarf_add () from /lib/libgo.so.4 #2 0xb745bd47 in ?? () from /lib/libgo.so.4 #3 0xb745c0e1 in backtrace_initialize () from /lib/libgo.so.4 This is a bit annoying, as I am unable to do some performance comparisons between Golang and C. Seems to be related with this [1] Debian bug report (GCC 4.7), from October. Is this an issue which is fixed in GCC already? Can you give me a workaround which I can use, so that I am able to compile with optimizations still? Or just hint me at the documentation which I 1) forgot to read or 2) was otherwise too stupid to get my hands on? Thanks! /Holger [1] http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=726794
