Summary: Just reporting what I found -- no questions asked


    I got the following message from my Microsoft C Compiler (4.0)
while trying to compile one of my programs (using LARGE MODEL and
MS-DOS):

    thisbug.C(8) : fatal error 1: Internal Compiler Error
		(compiler file 'regMD.c', line 272)
		Contact Microsoft Technical Support

    Here is a much reduced (and stupid) program fragment which still
produces the same result:

    int x,y,i;
    struct MemCell {int Ntype; struct MemCell *Mem} MemLoc[1000];

    void grokit()
    {
        while (i++ < 10) MemLoc[y].Mem[i] = MemLoc[x]; 
    }

    It seems that the following things are required
    - LARGE MODEL (compiles using SMALL)
    - loop (while, for,...)
    - Mem is not the first field of the structure
    - and of course this double indexing...

    I do not expect any help on this. I surely can code around the
problem. I'm just reporting a bug for anyone interested (whether
this reaches Microsoft or not, I don't care).  (Perphaps Microsoft
should have a mailbox in the net for this kind of things -- this
is much easier than going through the regular routes...). And,
perhaps this doesn't occur in MSC 5.0 or 5.1 any more...
