Hi wallbash,
  when you got a backtrace, you could source php-src's backtrace of php script

gdb > source path/to/php-src/.gdbinit
gdb > zbactrace 
then you may see a php level script, then we could find where cause the php crash

From the backtrace this seems a test for ext: intl, 
I can't install intl ext in my box because of compile issue.

@larucene, do you see some test skip for intl or did you enabled intl extsion?

Like stated on pecl: I sadly can't. Every output i generate or just executing that one test
case make the segfault go away.

I'm really sorry I can't provide anything more helpful but with issues like that (see the
last time I ran into something like that: https://bugs.php.net/bug.php?id=60825) getting a
good repro is really hard for me. I've tried for a couple of hours but gave up.

I totally understand if this is not fixable for you of course but asking in php.pecl encouraged me
to post it anyways :)

I can not reproduce this with 5.4-branch...

could you try to make a small reproduce test script ?  thanks
