We were able to eliminate these error messages and successfuly compile our code with g++-3.3.6 by using the '-frepo' option in our g++ compiles. I understand that this may not be the ultimate solution to the bug(s) being discussed here, but since we ended up here when searching for this particular error message, I'm adding this comment in case it helps other people. -- pfaff at mcmaster dot ca changed: What|Removed |Added CC||pfaff at mcmaster dot ca http://gcc.gnu.org/bugzilla/show_bug.cgi?id=16625

reproduces
either this problem, or a very similar one. It requires a mix of compilers,
and of optimization selections, to reproduce, though. One gcc 3 compiler and
one gcc 4 one should do it.

statement
case 3: return 999; break; // cases 3 and 4 can be coalesced
case 4: return 999; break;
}
return -1;
}
};

--- Additional Comments From marc dot price at rd dot bbc dot co dot uk 2005-06-27 14:31 --- Has this bug been fixed yet? Would really like to upgrade my linux box, but can't because this bug prevents me from compiling a vital suite of software. Can we bump-up the priority?
