I doubt his problem is related to the fpu bug in the pentium, since my system
has that fpu bug too, and I'm not getting this kind of problem.

Check /proc/cpuinfo to see if you have the Pentium bug (if so, get a
new CPU from Intel for free.)

However, I take it you're running an a.out system with libc 4.5.26 or
earlier; this is a well-known libc bug.  I'd suggest upgrade to ELF;
this bug is fixed in libc 5.
