Problem solved, posting here in case someone else somewhere in the world got
this error.
Somewhere up the function stack I didn't allocate enough room when using
MemPtrNew(), and wrote beyond the buffer I allocated room for (this is
unrelated to the txt parameter in the code example).
This caused a heap corruption, and, eventually, the crash.
