I tried that, but got the same error from dtrace as when using a return probe. Just \
that when using pid offset probes, dtrace refuses to instrument both function entry \
and return!

> dtrace -Z -n 'pid$target::dcntrl_:0 {@f[probefunc,probename]=count()}' -n \
> 'pid$target::dcntrl_:75f0 {@f[probefunc,probename]=count()}' -c myprog

 libdtrace DEBUG: creating probe pid18000:myprog:dcntrl_:0
 libdtrace DEBUG: error at 0x8b0 (assuming jump table)

 libdtrace DEBUG: creating probe pid18000:myprog:dcntrl_:75f0
 libdtrace DEBUG: error at 0x8b0 (assuming jump table)

Looks like this function is not too fond of being dtraced.
