HHVM randomly crashes (stackSize assertion fail)

[pjuke]

Hi.
I have compiled and install HHVM on Ubuntu 12.10, following the guide for 12.04.
I'm using the configuration file at http://www.hiphop-php.com/wp/?p=113, together with a index.php which contains ""

I start HHVM by issuing the following command:
sudo /home/eric/dev/hiphop-php/hphp/hhvm/hhvm --mode server --user root --config /etc/hhvm.hdf

But sometimes when I access http://localhost/index.php, HHVM crashes with the following error:
hhvm: /home/eric/dev/hiphop-php/hphp/runtime/base/string_data.h:246: void HPHP::StringData::checkStack(): Assertion `!m_data || (uintptr_t(this) - Util::s_stackLimit >= Util::s_stackSize)' failed.

Sometimes it works, sometimes it fails. I have no idea why, and I would really appreciate some help with this one. Seems like I'm the only one getting it as well, so I must be doing something wrong.

Thank you in advance.

Having the issues at well. Seems to be completely random and no idea what statements in a script of 3 lines is triggering it..

I'm having this issue too.

The error happens either on startup or during pageloads and is seemingly random.

I am facing a very similar issue too.

Not sure, what could be going wrong herewith.

Any pointers to last good known tag / references would be useful.

There seems to be a recent checkin that happened early last month.

$ git blame string_data.h | grep -C 5 246
f109b02 hphp/runtime/base/string_data.h (mwilliams 2013-02-11 09:51:46 -0800 241) * which maintains refCounts appropriately, and checks

f109b02 hphp/runtime/base/string_data.h (mwilliams 2013-02-11 09:51:46 -0800 247) }

Related to the assertion by any chance ?

Looks like the cmake build files got changed in an...inconsistent manner in the past month or so. The latest push should fix it.
