[Bug tree-optimization/20944] New: ICE: SSA corruption compiling ACE542 with gcc41

["micis at gmx dot de" <gcc-bugzilla at gcc dot gnu dot org>]

When I compile ACE 5.4.2 with the actual snapshot of gcc41 (gcc-4.1-20050410)
I get an ICE:

g++41 -O2 -c -o .shobj/Synch_Invocation.o Synch_Invocation.ii

Conflict s_4 and s_78 across an abnormal edge from BB40->BB43
Synch_Invocation.cpp: In member function 'TAO::Invocation_Status 
TAO::Synch_Twoway_Invocation::remote_twoway(ACE_Time_Value*)':
Synch_Invocation.cpp:49: internal compiler error: SSA corruption
Please submit a full bug report, with preprocessed source if appropriate.

g++41 -v:
Using built-in specs.
Target: x86_64-unknown-linux-gnu
Configured with: ../gcc-4.1-20050410/configure --prefix=/usr/local/gcc41g
 --program-suffix=41g --with-arch=opteron --enable-languages=c,c++
 --enable-checking
Thread model: posix
gcc version 4.1.0 20050410 (experimental)


This ICE doesn't occur at -O1 or with snapshot gcc-4.1-20050403.
