Internal compiler error 981006

[David Mazieres]

The following C++ code produces Internal compiler error 981006 with
the latest version of egcs 1.2.  It compiles fine with g++ 2.8.1, egcs
1.1, and earlier snapshots of the 1.2 branch.

% c++ -Wall -c -O 981006.C
981006.C: In method `void itree<int,timecb_t>::foo(const time_t &)':
981006.C:30:   instantiated from here
981006.C:19: Internal compiler error 981006.
981006.C:19: Please submit a full bug report to `egcs-bugs@cygnus.com'.

Thanks,
David
