What can be done with SIGSEGV in a third-party library or how to catch an error in my own?

Question

Qt

Greetings!
I'm working with a third-party library and after some time (no more than 10 minutes) it crashes into SIGSEGV
The debugger points to something in the library itself, but its code is closed.
Maybe I'm giving her something wrong.
Tell me, is there a way to catch SIGSEGV in c++ mingw 4.9.2 qt5 without crashing?
Or how can I understand what happens in the library if the debugger only refers to the asm code (I can’t understand what it doesn’t like because all the parameters and calls with sigsegv are the same as before and the debugger refers to different places O_o)?

Look here and here .
Also google for "signal handler".
