I've seen this happen before with mozilla and pheonix - it would run for a=
=20
few seconds, a window would maybe flash up for a fraction of a second=20
and then it would
quit without any error messages.   Running it through a debugger I saw
that it was actually segfaulting in a library function, but just never
showing any error messages.   I eventually realised that the compile
with optimizations had subtely broken it.  Recompiling it with an
additional -mfpmath=3Dsse sorted it, and mozilla worked.   It would appear
that fp code generation for athlon-xp is broken.  If you have added any
non-standard optimizations, you could try removing them and
recompiling.
