Bug (for real) in MS-C 3.0

[Kerro Panille]

I found a nasty bug in the MS-C 3.0 compiler the other day, and thought I
would tell everyone who might be interested in it. If you have MS-C 3.0,
give this program a try:

struct a
{
	int b;
};

void
funca( c )
struct a *c;
{ 
	int d= 1000;

	c->b *= 1000.0;  \
	c->b *= d;       /    Either of these lines produces the error
}

Then give the command:

cl -c test.c

You should get:

test.c(nn) : Compiler error (internal):Infinite spill

It seems that the compiler just doesn't like this simple structure. The manual
says that you "should never see this message," and tells you to write to MS
and report the bug. No mention about when you're going to get a fix. Fortunatly,
the work-around is obvious.
