The attached code fails with:
p...@dogbert> g++ -O2 -g -c mole_h2.cpp
mole_h2.cpp: In function void H2_LevelPops():
mole_h2.cpp:5:6: internal compiler error: in add_virtual_operand, at
tree-ssa-operands.c:638
Please submit a full bug report,
...etc.
p...@dogbert> g++ -v
Using built-in specs.
Target: x86_64-unknown-linux-gnu
Configured with: ../gcc450/configure --prefix=/usr/local/gcc450
--enable-languages=c,c++,fortran
Thread model: posix
gcc version 4.5.0 20090905 (experimental) (GCC)
(this is r151446). Note that there is nothing C++ specific left in the reduced
test case, however if you rename to mole_h2.c and compile with gcc, the bug
goes away. The "-g" option is necessary to trigger the bug. The code is
compiled correctly with g++ 4.4.1 and older.
