Mike Frysinger b2cae5d3f5 tst-fmon/tst-numeric: switch malloc to static stack space [BZ #19671]
The current test code doesn't check the return value of malloc.
This should rarely (if ever) cause a problem, but rather than add
some return value checks, just statically allocate the buffer on
the stack.  This will never fail (or if it does, we've got much
bigger problems that don't matter to the test).
