scheduler crashes in functional ticket calculation
on AMD64

The crash happens already with a few jobs (e.g.
200) when functional tickets are set to a non-zero
value and functional shares are configured for a
few projects, users and departments.

There is a strong indication of a heap corrpution
since the crash occurs in completely different
functions. Also a busy infinite loop in the
malloc() call has been seen.

So far it only could be reproduced on Linux AMD64.

The crash also happens in SGEEE 5.3p5.

Tested under solaris64 and does not crash!

I think it is fixed. At least it did not crash anymore after
my changes, but I did not understand the bug.
