>Description:
I tried dtrace -p <pid> -n 'pid$target:libc*:malloc:entry', but it didn't match any probes.  dtrace -p <pid> -n 'pid$target:libc.so.7:malloc:entry worked.

On the other hand, dtrace -p <pid> -n 'database*:::' did match probes.  Go figure.

I cannot reproduce this problem on CURRENT. It has likely been fixed by 
one of the recent libproc changes.
