which version of pgcc did you use? I will tr that with my copy of mozilla as
time permits.

Well, I can remember that I have removed one abort() in gcc over the time. In general,
the abort() indicate that there is a bug in a previous pass. It might or might
not manifest itself in broken code.

The problem is, all versions of mozilla I compiled myself never
succeded to open a window before they coredumped, so I can't regularly
check mozilla ;(
