When I compile ace542 with the actual snapshot (20050806) of gcc41 I get an ICE when I use: -O3 -g -floop-optimize2 -ftree-vectorize. last working snapshot is: gcc-4.1-20050723 first failing snapshot is: gcc-4.1-20050730 Michael Cieslinski g++41j -O3 -g -floop-optimize2 -ftree-vectorize -c -o .obj/Proactor_Test_IPV6.o Proactor_Test_IPV6.ii Proactor_Test_IPV6.cpp: In constructor 'Connector::Connector()': Proactor_Test_IPV6.cpp:925: error: definition in block 6 does not dominate use in block 9 for SSA_NAME: TMT.3445_18(ab) in statement: TMT.3445_58(ab) = PHI <TMT.3445_57(ab)(3), TMT.3445_18(ab)(9), TMT.3445_57(ab) (11)>; PHI argument TMT.3445_18(ab) for PHI node TMT.3445_58(ab) = PHI <TMT.3445_57(ab)(3), TMT.3445_18(ab)(9), TMT.3445_57(ab) (11)>; Proactor_Test_IPV6.cpp:925: internal compiler error: verify_ssa failed Please submit a full bug report, with preprocessed source if appropriate. g++41j -v Using built-in specs.

The first preprocessed file produces the same ICE as PR 22228.
Both testcase give the same on ICE on x86, this is a dup of bug 22228. *** This bug has been marked as a duplicate of 22228 ***
