I had this very same MCH with a old ILE/C program written a year or two
back when I compiled it on V4R2. The weird thing was I could run the
program once and it would work, run it the second time (no changes just
F9 and enter) the program would fail, run it the third time it would
work. Alternate executions would fail. Turned out to be that the C
runtime realloc() function was failing if the pointer was not explicitly
set to null the very first time the call to realloc() was made.

I fixed the code to ensure the pointer was initialized (even though it
was being initialized to null) and the pgm worked every time. The reason
(yes there is one!) I'm telling you this is that the pgm *never* failed
in a debug session. May help you...
