realloc() can abort when it finds out that the internal data
structures controlling memory allocations are corrupted.
It should also print an error message to stderr when this
occurs.
This is generally caused by earlier buffer overruns in user
code. The fact that the problem is detected when realloc()
is called from postgres code does not imply that
the problem originates in postgres code.
To locate the bug, it may help to run your application with valgrind.
