This sounds familiar Frown | :(

Sometimes it happens to me too. I write a program thinking I covered all possible breakage points and, when I go debug it, it crashes and takes GDB with him. Side effects can be very nasty and naughty Sigh | :sigh: .

From my limited experience, if you are checking for out of range, null and other usual checks, this usually comes down to some uninitialized variable or some math using the wrong variable/operation.

Sometime ago I spent almost one month inserting prints into a somewhat large program because whatever was wrong with it also crashed GDB. The program started fine and after e few iterations (randomly between 100 and 1000 depending on input) bam!

It ended up being both an uninitialized temporary variable and a missing dot (decimal place) in a formula that caused an unsigned int to overflow (to a smaller value than it should), that then caused the result of the next formula to be negative when it shouldn't and cascaded out of control from there. Never found out why that would crash the debugger!

Now I try to have a debug only log that prints/dump non temporary variable state to a binary file on every iteration, just in case.

My advice would be for you to start by double checking variable initializations and formulas for correctness.

Good luck
