[FLASH-USERS] Run time error?

[Ryan Farber]

Hi Hava,

That'd be very difficult to determine with that traceback! I'd recommend
compiling FLASH in debug mode as a start to have a traceback to work with
and then you can work with (parallel) debugging tools too. Or if the error
is late in the evolution (or disappears during debug mode) add print
statements to understand the order of execution and where the segfault
occurs. Often my segfaults are related to indexing out of bounds - but
other causes are possible too.

Best,
--------
Ryan
