Bug report

[Jan Dvorak <johnydog at go dot cz>]

Hi,
gcc shows me ICE when compiling file ArenaReplay.cc from
http://download.sourceforge.net/RealTimeBattle/RealTimeBattle-1.0.3.tar.gz
i simplified to few routines, so it still reports the same error. I've
attached that simplified file preprocessed. ICE was reported by 
cvs 20000408 and by current cvs (20000420), when this file was compiled
with 
-O2 or greater. When used -O1 the file was compiled successfully.

Command line:
g++ -O2 -c ArenaReplay.cc

Error:
ArenaReplay.cc: In method `void ArenaReplay::parse_log_line_forward
ArenaReplay.cc: (char)':
ArenaReplay.cc:43: Internal compiler error.
ArenaReplay.cc:43: Please submit a full bug report.
ArenaReplay.cc:43: See <URL:http://www.gnu.org/software/gcc/bugs.html>
ArenaReplay.cc:43: for instructions.
