How do I set up gdb on window so that it does not allow a program with assertion failure to terminate? I intend to check the stack trace and variables in the program.
For example, running this test.cpp program compiled with MinGW ‘g++ -g test.cpp -o test‘ in gdb:
#include <cassert>
int main(int argc, char ** argv) { assert(1==2); return 0; }
Gives:
$ gdb test.exe

I would like to be able to stop the program from terminating immediately, like how Visual Studio’s debugger and gdb on Linux does it. I have done a search and found some stuff on trapping signals but I can’t seem to find a good post on how to set up gdb to do this.
Just set a breakpoint on exit:
(gdb) b exit
