Because, the CRC value in the NMEA sentence is only 8-bit, it is fairly easy for a bad message to get past the CRC check.
By observation, with my GPS on the window it takes on average ~3 hours before a bad message crashes the program.

This is usually triggered by _parse_int and _parse_float functions and can happen elsewhere.
