ALLOC and REALLOC error.

[David Morris <dmorris@xxxxxxxxxxxxx>]

We have a program that receives an error CEE0810.  The starting address for 
reallocation is not 
valid.  It seems to depend on the order of ALLOCs.  I ALLOC 5 pointers and then 
REALLOC the 3rd. 
and 4th.  The 4th. pointer allocated always gets this error.

ALLOC  600  pA
ALLOC  48     pB
ALLOC  1200 pC
ALLOC  96   pD
ALLOC  600  pE

REALLOC 1800 pC
REALLOC 144  pD Receives error.

ALLOC  600  pA
ALLOC  48     pB
ALLOC  96   pD
ALLOC  1200 pC
ALLOC  600  pE

REALLOC 1800 pC Receives error.
REALLOC 144  pD Never get here.

Changing the order of REALLOCs has no effect on which pointer gets the error.  
Changing 
the order of ALLOCs does have an effect.  After the allocates I wrote down the 
pointer 
values.  The pointer values do not change between the allocate and reallocate.  
I also set 
watches that confirm this.  The allocates and reallocates occur in different 
subprocedures 
called from a single procedure which passes the pointers as a parameter.  The 
modules are 
not optimized.

Any ideas?
