Segfault with Apache2 / Wheezy
Opened this issue · 2 comments
When trying out tls interposer on a Debian Wheezy machine, I have encountered a persistent (and 100% reproducible) blocking segfault when restarting apache. It seems the segfault is in libonig.so (Onigura Multibyte chars), which is required by libapache2-mod-php5.
I'm using stock Apache2, stock PHP5 (with Zend OPCache) and the current Interposer with debug and logfile as the only non-default options. This is the backtrace for the segfault:
arning: "/usr/lib/debug/.build-id/84/bee3ec119629745f1abb696a297d23ef52d3ba.debug": separate debug info file has no debug info
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
Core was generated by `/usr/sbin/apache2 -k start'.
Program terminated with signal 11, Segmentation fault.

I'll look into it. However, as I currently don't have a Wheezy setup, this might take some time.
I can provide you with a VM if that helps?
