Hi Ben,
This new crash was also fixed - see
https://github.com/OpenSIPS/opensips/commit/34f81b223fb466ecddf648f72f615ab24d4a86dc
.
Do you have any more crashes on the pipe to report :D ? I'm getting warm :)
Thanks and regards,

Unfortunately, I have had another crash during testing. I was not able
to capture the core, but I did get this log:
Feb 28 03:35:22 [359] CRITICAL:core:qm_debug_frag: qm_*: prev. fragm.
tail overwritten(c0c0c0c0c0c0c020,
abcdefedabcdefed)[0x7fa6cd6c46b8:0x7fa6cd6c46f0] (del_uri_param,
checks.c:242)!
Feb 28 03:35:23 [353] INFO:core:handle_sigs: child process 359 exited
by a signal 6
I am making adjustments to be able to collect the core if the crash
occurs again.
Thanks,
Ben Newlin

Bogdan,
I found this previous thread that has this error:
http://lists.opensips.org/pipermail/users/2016-October/035635.html
The fix suggested there worked. When I removed the quotes around the
regexp used in re.subst the crash did not occur.

Bogdan,
I just tested it and that crash is no longer occurring. However I am
now seeing a different crash, but it seems to still be related to regexp.
Feb 27 19:07:17 [369] ERROR:core:subst_parser: string too short
Feb 27 19:07:17 [369] ERROR:core:tr_eval_re: Can't compile regexp
Feb 27 19:07:17 [369] WARNING:core:do_assign: no value in right
expression at /opensips/control.cfg:1952
Feb 27 19:07:17 [361] INFO:core:handle_sigs: child process 369 exited

Feb 27 19:07:17 [361] INFO:core:handle_sigs: core was generated
Feb 27 19:07:17 [361] INFO:core:handle_sigs: terminating due to SIGCHLD
The do_assign error makes it seem like there may be something wrong in
my script, but I can’t see what it is. And I’m not sure what the
“string too short” error is either or why the regexp could not be
compiled. It looks valid to me.

Hi Ben,
I just committed the fix for this - could you update from GIT and give
it a new try ?

OK, to be more precise, the crash is around an "If" statement
where you have in the condition an REGEXP test (=~) with a
left operand translated into "downstream" (maybe a $DLG_dir ??).
Does it sound familiar to you :) ?

Yes, that is from that exact file, line 435. It’s just a
return statement. I can send you the file off-list if
you’d like.
I do use the $DLG_dir in my script in a few places, but
the only one this crash would have hit is in some logging.
