Description

Segmentation fault when using php when xdebug

Additional Information

A few days ago while I was working on a project I encountered a segfault while making a request to the builtin Symfony server.
restarting the server didn't help. I disabled loading of xdebug and everything was working again. Tried to reenable it and the problem seemed to go away. Half an hour later I tried to update the DB schema and segfault was back again.

The issue was captured by abrt and I reported it directly to Bugzilla.

the version of PHP is 7.3.6, but I can't see to find it in the selector

Hello,
I wasn't able to come up with reliably reproducible setup, but i managed to limit it by reducing the configured items.

with the config below, it was happening:

xdebug.var_display_max_depth=8
xdebug.var_display_max_data=2048
xdebug.var_display_max_children=256
xdebug.profiler_enable=0
xdebug.profiler_enable_trigger=1
xdebug.cli_color=2
xdebug.collect_assignments=1
xdebug.collect_params=3
xdebug.collect_return=1
xdebug.collect_vars=1
xdebug.dump.POST =
xdebug.dump.GET =
xdebug.remote_enable=1
xdebug.remote_autostart=1
xdebug.show_exception_trace=0
xdebug.trace_enable_trigger=1
xdebug.extended_info=1

i reduced configuration to :

xdebug.profiler_enable=0
xdebug.profiler_enable_trigger=1
xdebug.cli_color=2
xdebug.remote_enable=1
xdebug.remote_autostart=1
xdebug.trace_enable_trigger=1

and seems that the problem is not happening

Is this still an issue with Xdebug 2.9.x?

I can't recall having this issue recently, so i would say no, it is not an issue right now .
