I would be very leery about using the program.  I don't think you actually
solved the problem, just hid it.  You should use the standard malloc
functions and track down the problem that is probably in your code.  I 
say that the problem is probably in your code because there are hundreds
of programs on the system that use the libc.a malloc without any 
problems.

The correct way to fix this problem is to track down the cause of the 
memory fault in your code.  A 12K program is not a very large program
and should be somewhat easy to debug.
