dtrace discuss - May 2008 - Next finding about DTrace in MySQL

Hi,
My next finding about an application where I tried to have 2  
providers in the same binary.
If I put the ndb_blocks provider first I get access to all of those  
and when I have ndb_vm I
get access to that provider but not to both at the same time (I''ve  
seen both before so I gather
this is another DTrace bug).

This is a bug, and I believe it has been discussed previously on the list,
but I can''t seem to track down the bug ID.

So with this limitation and the limitation that dtrace -G -s only  
applies to object
files and not to libraries the only workaround I find is that one  
needs to build all
object files in them same directory as the binary or can anyone come  
up with
a different workaround.

When Adam comes online later today I''ll have a chat with him
about these issues. One of us will pick them up.

We''ll contact you offline.
