When a program crashes the last thing that happens is that its memory
image is written to a file called core. Some shells allow to specify
how big such core files may be; bash uses "ulimit -f <#kilobytes>".
Default the max size is 0, so practically prohibiting core dumps.

when the program crashed lookout for a file called core in your home dir
or in the dir the program started from.
