This is probably a red herring. The 'B' modifier used in the patch does
not put the argument unless it's true to the monitor.

I traced the problem to a bug in commit 8d9ca6cdb3a58414 where I've
changed 'nstats' to a pointer but did not fix the usage in the macro
which gathers the stats. This means that the expanded code was
incrementing the pointer which was not dereferenced aferwards rather
than the value itself.

I'll post a patch soon.
