Re: Bug plperl.c

Hi Tom,

Wow that was fast!

Upon further testing, my path isn't a full fix... there's other parts of 
the flow that needs current_call_data


I trimmed down my example from the guts of a complex application. Sorry 
I didn't re-test with the trimmed example.  But the use-case is very 
much the same... it has to do with running spi_exec_query during parse time.

I'll work on redoing the example to reproduce the crash.
