Command line:
g++ -O1 -fpeel-loops -fcompare-debug -c testcase.cpp
it has to be compiled as C++ code, even though it's valid C code
Tested revisions (x86_64):
r155680 - crash
r155662 - crash (x86)
r154886 - crash
r154830 - crash
r153685 - OK (built without graphite support, if that matters)
Output:
$ /mnt/svn/gcc-trunk/binary-155680-lto/bin/g++ -O1 -fcompare-debug -fpeel-loops
testcase.cpp -c
g++: testcase.cpp: -fcompare-debug failure
Valgrind:
no errors reported
