The guest account was temporarily broken.

It isn't perhaps a 64-bit system?
no it's i396 not ia64. But, a friend had same problem with ia64 and gcc-4.2

Yep. Optimisation -02 cause this problem ?? If it's not written in my bug report, I have tell a big mistake. I use allways this option for packaging freeciv in .deb than to debian maintainer, but if there are no mentions of it, then -O2 was not the problem, was only
gcc-4.2.
Really sounds to me like this is a glib bug.
Really, I can't answer since it's working with other compiler (3.4 on msys and 4.2 on linux). Bug still remains if you change version of glib (tested with 2.8 and 2.10). I had same problem long time ago with g77 (fortran code). Community of 250 people cannot find in library where we are wrong. Just changing compiler closed the problem.
