[Bug optimization/13066] New: ICE in in invert_truthvalue, at fold-const.c:2554

[bryner at brianryner dot com]

I pulled a tree from tree-ssa-20020619-branch today and got the following ICE
when compiling some Mozilla code:

$ c++ -Os -o nsScriptSecurityManager.o nsScriptSecurityManager.i
../../../../mozilla/caps/src/nsScriptSecurityManager.cpp: In member function
`nsresult nsScriptSecurityManager::CheckSameOriginPrincipalInternal(nsIPrincipal*,
nsIPrincipal*, PRBool)':
../../../../mozilla/caps/src/nsScriptSecurityManager.cpp:807: internal compiler
error: in invert_truthvalue, at fold-const.c:2554

The ICE occurs with -O1,-Os,-O2, but not -O0.
