fc 3 and can't run mozilla or firefox

[Richard Hubbell]

This is a very plain fc3 system, no KDE or Gnome, just xdm and xfce.
When I try to run mozilla or firefox they both sigsegv.  Running in gdb
tells me that firefox dies at JS_dtostr and mozilla dies at PR_dtoa

They seem to be the same symptom.  Any ideas?

I tried as root also just in case it was a permissions problem.

Am I missing some library or something like that?
