Ok, I can reproduce it. And that means your settings and all are ok.  
However I do not have a solution. Best to ask on the fpc mailinglist.

This is what I found.
- It only happens with "reallocmem" (probably other similar commands)
- It works fine, if you create a leak as follows "TObject.Create;" (and 
never free it)

Reallocmem is NOT inlined

But, from looking at the assembler code, it seems that it does not setup 
a stackframe as other code does. I **guess** the stuck dumpng code has a 
problem with this minimal frame.
