This bogus size of -1 is causing an informational warning from VMS Debug on
IA64 VMS.

I patched gnatpro gcc-head snapshot from 20100307 with "ppa" (less ada bits) as
instructed in comment #33, and it bootstraps fine on alphaev67-dec-osf5.1b,
also compiles p.ad[bs] aka "p.txt"

I'm not sure what Jan is asking for exactly, but in an attempt to be helpful
here is a traceback using the 20091124 sources for the reduced testcase on
alpha-openvms. The debugging info is messed up for me too, but its just the
source line correlation records numbers, the call stack looks reasonable. If I
can be of further assistance please ask.
