Hello everyone!
I posted php code of the test script in earlier posts. The problem is 
the same.
Gdb crushed if I tries to run php script under gdb. So I created core 
dump and feed it to gdb as Olly advised.
I attached gdb backtrace.
I don't understand it absolutely. But my worries are about "static npos 
= 18446744073709551615" in #1. I think it is the upper limit of long, 
right? is it ok?
Please advise.

Thanks,
Vaso.
