Can you reproduce it?
The PHK implementation of the memory allocator has a very nice feature:
Have a look at the malloc(3) manpage, search for "malloc.conf". This
"file" is a symlink and its content lists options to tune malloc()'s
behaviour. Alternatively -- or to influence an individual process only
-- you could set the MALLOC_CONF environment variable. A third option
is to change the program's source and adjust a global _malloc_options
variable in the process.
All of the above methods allow you to instruct malloc(3) to not just
issue the message, but to abort() the process and generate a core dump
so you can do a post mortem analysis and see what happened.
If you don't understand or are scared by any of the above
ask your parents or an adult to help you.
