As I see now, there are also an other person who has problems with "-pg"
programs. So I will describe here my situation (But I had this problems
also with V2.00)

I had the idea to profile RHIDE and so I compiled some files with "-pg"
and linked it also with that switch.

Now I run RHIDE on the project for RHIDE and did a 'Make' because I
wanted
to get the profiling information about the check of the dependencies.

After a few seconds (many disk accesses because of getting the timestamp
of a file and reading the contents of a directory)  the program
chrashed.
(Because I run under W95 only the DOS-box).
OK. now I started again and it worked a little bit longer (probably
because
of the disk cache of W95) and then the same crash.
If I repeated the above many times I came to an successfull end.

In my opinion there is somewhere (but please do not ask me where, I have 
search already for it, but no success) in the profiling functions code,
which is executed via an interrupt but not correct locked?
