configure --disable-gcc-vcheck appends -O0 to your compiler flags, and -broken-compiler to your clamav version. So its normal that all tests pass: they are no longer compiled at -xO3. All the tests, including those that check for a gcc bug, and the one that checks for CLI_ISCONTAINED, checks for code that is miscompiled. It doesn't matter if its gcc or not, if the code is miscompiled, the compiler has a bug. The ones called "checking for gcc bug ..." are called like that because the testcase comes from the gcc bugzilla, and (in theory) shouldn't affect any other compiler than gcc 4.0.x and 4.1.0, but you never know.
