Modified: test testmem.c
Log:
This adds Sanders suggestion of testing the reset for the tracking memory
system. This also exposes a problem in that code where free is called twice
for the same piece of memory, generating a segfault. Using some extra
debugging
This is what I see...
Tracking Memory
Creating the memory area............................OK
Creating 10 lumps of memory, each 1024 bytes........OK
Writing to the lumps of memory......................OK
Check what we wrote.................................OK
About to reset the tracking memory..................
calling free on 800259a8
calling free on 80025598
calling free on 80025598
I don't have tim to investigate in more detail at the moment.
NB this will segfault, but it's being committed to allow people to
see the problem themselves :)
