Note sure if this will be useful, but if i edit main/php_config.h
(after running ./configure) and remove all LOCALE defines, here's a
backtrace of the segfault:

[EMAIL PROTECTED] :
Can you try that again, but when you hit the segfault,
type the following commands into gdb:
up
print locale
print pce
print pce->locale

Still getting the segfault at almost the same place. Seems a lot
easier to reproduce now.
