Repeated use of http_request cause a crash related to the storage of the result in a PV.
Will upload backtraces and other info to this issue. If anyone else have seen this please add info to this bug report.

Is it latest 4.3 or master? There were couple of fixes in September, iirc.

Backtrace from the curl module in dev. Looks similar with the http_request in 4.3

Please @oej use the markdown '```' in order to paste this kind of things. Usually data get detected as references for issues like in #5

Thanks maniac :-)
I am a bit at loss here, have looked at this backtrace for far too long and can't figure out what goes wrong. It happens now and then and is not easy to repeat with a single request, so it feels like a memory leak or slow corruption somewhere.

It is a buffer overflow -- apparently curl module doesn't have the at least 558a65e48e6819140b409cf58a0340aa78b8c2cf
See the last commits to the utils module in 4.3:
``` git log -p modules/utils/ ```

Hi @oej , Have you had any further issues in the curl module since my fixes went in?

Closed #400.

Closing this one as fixes were pushed more than a month ago -- if there are new issues, re-open or create a new one.
