I caught a bug in my program. it was a non thread-safe function in json-c library. I knew there were some non thred-safe functions, but did not expect that json to string serializer could be non thread-safe and I did not wrap it in mutex locks.
the segfault problem is solved and it was not in PostgreSQL where it seemed to be. such uncertain bugs sometimes happen.
but now the question is to write a thread-safe version of json-c. I cannot tolerate so many locks for every parsing-printing operation. I could not find thread-safe json library and looks like I have to write it myself. well, not from the scratch, but taking json-c as a base, I think.

#rust will become an absolute laughing stock if it speaks about #programming #security while outsourcing development of #rustlang itself to the NSA's foremost partner. Either dishonest or utterly clueless.
 
damn, I rebuilt all libraries with debug options to find out where exactly segfault happens and what causes it. and, of course, the segfault disappeared. cannot get it again with debug libraries :) this is a usual effect in software. debug works slower and may be more stable than release.

I faced a strange thread-related segfault in libpq. in musl, I must add, because this may be a problem of glibc non-standard behavior that often is used in code and then programs fail on musl. I will run the test in glibc chroot too, just to get sure it's not a principal bug in the library code.
but for a while I cannot say where exactly it is. program fails in PQfnumber when another thread exits poll in PQgetResult. it happens not often, I tested my utility on high load requests traffic and at 40 000 requests per second it happens once in an hour or so. I'm sure that this should not happen because threads use thread local DB connections. but it does. the past night I caught 3 core dumps with the same segfault conditions and now have to debug PostgreSQL library to find out what the problem is. not that I'm too happy to do this but I have to.
