[Bug middle-end/42068] [4.5 regression] ICE in function_and_variable_visibility with static common vars.

["rupp at gnat dot com" <gcc-bugzilla@gcc.gnu.org>]

------- Comment #32 from rupp at gnat dot com  2010-01-21 17:36 -------
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.
