[Lazarus] Shared libraries, cmem and heaptrc

[Mark Morgan Lloyd]

Before cautiously tackling a shared library, I thought I'd have a trial 
run with cmem in the program that's going to call it. I find that if I 
put 'cmem, heaptrc' at the start of the .lpr it runs and I get heaptrc 
output, /but/ one of the files has a wildly erroneous error number.

If I remove both cmem and heaptrc from the .lpr  I still get the error, 
despite having carefully removed all binaries etc. Is there a cache 
somewhere that also needs to be cleared?
