Could you do a "print func_name" instead of "bt" for me?

Hmm, that is sorta useless :) Could you perhaps hand me over a (short) test
case that exhibits this problem?
----------------------------------------------------------------------
mhorvath - 2007-10-30 15:22 CET
----------------------------------------------------------------------
Hm, I kindly don#t know, which test is responsible for the issue ... and I
cannot send you over our sources because of IP issues ... any other way to
help resolving the problem?
:(

Not really, unless you want to spend some time to make a short reproducable
case out of this. But your first comment shows a stop in
zend_language_scanner... not in Xdebug. Did you interrupt it or something?
Try to do the print func_name when the segfault occurs...
