Re: Brain fart alert

[Nicolas <nikos42@xxxxxxxxx>]

Hello,

I can't reproduce the segfault on i386 anymore (I updated my system
since last time I tried), but I got a new brain fart alert, with the
attached example.

As previously to reproduce: g++ -g -c brainfart2.cpp -o brainfart2.o &&
pahole brainfart2.o

Thanks a lot,
Nicolas
