That's an odd occurrence. Parrot::Ops2pm::Utils::new has:
if ( !$flagref->{dynamic} && !-d $incdir ) {
mkdir( $incdir, 0755 )
or die "ops2c.pl: Could not mkdir $incdir $!!\n";
}
There's a race condition, if that directory doesn't exist and multiple
processes execute that code simultaneously. Fortunately,
Parrot::Ops2pm::print_module() creates that directly when it writes
Parrot::OpLib::core -- the only file in that directory.
Fixed in r32016.
