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.
