[OpenSIPS-Devel] OpenSIPS/master is broken since 2 days ago

[Maxim Sobolev]

Hi,

I've noticed that OpenSIPS/master is now crashing during our voiptests run
since about 2 days ago with the following message:

Jun 26 23:50:33 [22691] CRITICAL:core:qm_debug_frag:  qm_*: prev. fragm.
tail overwritten(646573755f78616d,
abcdef657a69735f)[0x7f2eb37a3b30:0x7f2eb37a3b60] (register_stat2,
statistics.c:407)!
Aborted (core dumped)

I have not got time to dissect it down to a specific commit, but maybe it's
something obvious. Builds are triggered by cron, not by a specific commit.
The last known successful run was revision f682abe530, the first know bad
revision was 82c446d2922f, so the issue in question has been introduced
somewhere in between those two. Possible culprits are:

could be something else. Full failed test log can be found here:
