Let me check and fix if necessary, but that's in libintl not in php :)
Thanks for the feedback!

Ok, I checked the LANG environment variable, and it is unset.
If I do set it (set LANG=esp), then test script doesn't crash. If I
unset it again (set LANG=) then it crashes again.
I think that in out application we could be trying to translate some
string before gettext environment is set up, so this could be the reason
to our application crashing.
Anyway, seems PHP should not crash if no LANG is set? :-)

Sorry, I copied the wrong backtrace (it is a yesterday backtrace).
There is no translation for the string.

No idea what's wrong on your config but gettext works just fine here.
Does it crash when no translation data are used? (no po) Or only when it
actually does the translation? If the former, pls send me the
translation data
so I can try to reproduce your problem.
Also the backtrace for VC9 looks wrong, it should not use msvcrt at all
but the
VC9 versions. It looks to me that there is a DLL mess on your box. Such
DLLs
mess causes free/heapfree crashes as different crt are use to alloc and
freed a
given resource.

VC6 thread safe version version due to Apache. The backtrace has been
generated from CLI using VC6 ts.
I just tested the script with VC9 on the cli ts and it also crashes.
