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.
