gcc version 3.4.3
happened with my previous systems too (not sure anymore but i think it was
gcc3.3.3 and 3.4.1)
Happens with default qemu default optimization :
-Wall -O2 -g -fno-strict-aliasing
when setting to -O0 it compiles, but doesnt work (segfaults during runtime)
the error during compilation is:
target-i386/op.c
