I have a problem using the Munger Toolbox utility. I want to set two relocatable
buffers, one to receive data, the other to hold a copy. The way I make a copy is
to use the Munger routine with an offset of zero, ptr1=NIL, len1<0. I make the
call and the second buffer is filled to the correct size, but occasionally the
the data in the second buffer doesn't match the data in the first. I notice that
when this happens, 4 contiguous bytes have garbage in them (in the copy buffer).
The position of the 4 bytes varies within the buffer. This happens infrequently,
but does happen. This problem also happens occasionally when I concatenate two
buffers. The call looks straightforward. Is there something I have to do first?
Am I missing something?

Any help would be appreciated.
