If it's a stack-based variable or function parameter then you could use padb, a link is in my signature.  Assuming you only have one parallel job running then the command line you want will be:

$ padb --stack-trace --tree -Ostack-shows-locals=1 -Ostack-shows-params=1 --all

If you have more than one job active then replace --all with the jobid.
