I was wondering where the count would go.

It strikes me that the pattern needs to be {3,} or maybe just +.
I dunno what this column is measuring, but if we are past 0xA00
then surely 0x1000 is not far away.

http://msdn2.microsoft.com/en-us/lib...85(VS.71).aspx appears to
suggest that the size of the field is fixed.

But who knows?

That would imply that dumpbin fails at 4096 symbols per file. While I
surely wouldn't put it past M$ to have put in such a limitation, I think
it's more likely that the documentation is badly written.

In any case it would be easy enough to make up a quick test to see what
happens with say

void func1() {}
void func2() {}
...
void func5000() {}

Yes, it starts with 3 and goes to 4 digits above FFF

OK, then {3,} is the right quantification. Will fix.
