[SR-Users] kamailio 4.4.1 DROUTING module memory leak ?

[Daniel-Constantin Mierla]

Hello,

can you try with the patch from this commit:

  -
https://github.com/kamailio/kamailio/commit/e0f95ea7fc691f976564b07436848673c633195d

The memset() is optional, more for long term safety, the if block at the
end of the function is relevant.

In 4.4, the file to change is modules/drouting/dr_time.c instead of
src/modules/drouting/dr_time.c.

If all is fine, then I will backport it.

Cheers,
Daniel
