Previously code in the SWIG tool didn't handle allocation failures well. Most places didn't check for NULL return from malloc()/realloc()/calloc() at all, typically resulting in undefined behaviour, and some places used assert() to check for a NULL return (which is a misuse of assert() and such checks disappear if built with NDEBUG defined leaving us back with undefined behaviour). All C allocations are now done via wrapper functions (Malloc(), Realloc() and Calloc()) which emit and error and exit with non-zero status on failure, so a non-NULL return can be relied upon. Fixes #1901. |
