g++ -O1 -fprofile-generate gcc-bug/test-case.ii
gcc-bug/test-case.cpp: In function int f(const int*):
gcc-bug/test-case.cpp:14: error: address taken, but ADDRESSABLE bit not set
D.27568
gcc-bug/test-case.cpp:14: note: in statement
D.27611 = &D.27568;
gcc-bug/test-case.cpp:14: internal compiler error: verify_stmts failed
It is very simple code that I have used in C++ for a long time.
Like this:
std::copy(&array[0], &array[5], ostream_iterator<int>(cout, "\n");
I accidentally built GCC 4.5.0 from SVN instead of 4.4 (it branched when I
wasn't looking) and hit this bug.
It only seems to happen with optimization and profile generation. -O1
-fprofile-generate will trigger it. -O3 without profiling will not.
I have not tried to reproduce with GCC 4.4 or GCC 4.5 on i686 or x86_64.
Preprocessed source will be attached.
