Can you please run that command in the debugger and see what is going on?

>From the symptoms it might be that emacs calls a libc function that
returns malloced memory, and then it tries to do a realloc on that. 

A similar problem is solved by the BROKEN_GET_CURRENT_DIR_NAME
in src/s/aix4-2.h

Can you verify if this issue is malloc related?
