Summary: Too many phpunit tests causing segmentation fault
Status: Feedback
Type: Bug
Package: PCRE related
Operating System: ubuntu 16.04
PHP Version: 7.1.3

New Comment:
I installed the dbgsym packages for all of the 7.1 packages I have installed, the output from the
backtrace looks a little bit more helpful, but still a lot of references to xdebug.c:1995. I'm
currently still running "USE_ZEND_ALLOC=0 valgrind php vendor/bin/phpunit" and will stick
the output up on pastebin once it's done.
Here is the pastebin link for the backtrace, looks easier to read on pastebin https://pastebin.com/TXBABZD5

*-dev packages does *not* contain debug-symbols
they are for building extensions and contain headers and so on
https://wiki.ubuntu.com/Debug%20Symbol%20Packages

After installing the debug symbols, could you please also provide the output of
"USE_ZEND_ALLOC=0 valgrind php vendor/bin/phpunit"? (It might take a few minutes to run.)

This happens in pcre_split, which is the pcre extension.
Your PHP doesn't have symbols available, but Xdebug does, that's why you see it so often.
If you have installed PHP through Ubuntu's packages, also install the php-dev (or php-5dev, or
whatever it's called), to provide a useful backtrace.

In case it's required the xdebug extension version is Xdebug v2.5.1

Here is the backtrace. I have tried to reproduce outside of the code base where it has occured, but
couldn't replicate it. I've changed the package to Xdebug as it looks like this is where
the issue is occurring according to the backtrace. I'll try again to see if I can get a script
which will reproduce the error.
