You don't really need to know the details of the core file format, you
just need the core file and the corresponding binary and you can debug
this with GDB.  See:

  https://sourceware.org/gdb/current/onlinedocs/gdb/Invoking-GDB.html#Invoking-GDB

Basically you want:

  $ gdb application.exe core.file

Then you should be able to investigate the state of the target at the
time it produced the core file.

Good luck,
Andrew
