------- Comment #4 from tbm at cyrius dot com 2007-03-08 09:03 -------
I have a fairly small C++ testcase for what appears to be the same issue:
(sid)3604:tbm@em64t: ~] g++ -c firebird2-nav.cc
(sid)3605:tbm@em64t: ~] g++ -c -O firebird2-nav.cc
Unable to coalesce ssa_names 27 and 10 which are marked as MUST COALESCE.
result_27(ab) and result_10(ab)
firebird2-nav.cc: In function 'BOOLEAN NAV_get_record(Rsb*, mfb*, RPB*,
RSE_GET_MODE)':
firebird2-nav.cc:235: internal compiler error: SSA corruption
Please submit a full bug report,
