I'm not quite sure that's a safe assumption.

This is blatantly not true. I just checked it. Cmon, do you really think MSVC would
have screwed up the PRECEDENCE rules?
CBP* pPlayer = NULL;
if( !pPlayer || !pPlayer->IsNetClient() )
{
printf( "MS can write a compiler!\n" );
}
Compiles and prints out the statement, as it should.
I'd say the most likely explanation is indeed shimms' and hofer's conjecture, i.e.,
that it has not been initialized. There is no serious compiler that will not follow
the left-to-right rule, that's a fairly integral part of the C++ specification, which
is used a lot (it's used throughout the HL SDK, for example), and certainly they all
follow the correct precedence rules.
