Any buildbots building clang/llvm with gcc?


Are there any buildbots that build clang/llvm with gcc and run tests nowadays?

When testing our out-of-tree target we are regularly building the compiler with both clang and gcc and lately we have noticed an increasing number of problems when using gcc which the rest of the community doesn't seem to notice?

E.g. for some days now at top-of-tree, if building with gcc 4.9.1 or 5.1.0 one test case fails with SEGV:

FAIL: Clang-Unit :: ASTMatchers/ASTMatchersTests/IsAnyPointer.MatchesObjcPointer (8218 of 25131)
******************** TEST 'Clang-Unit :: ASTMatchers/ASTMatchersTests/IsAnyPointer.MatchesObjcPointer' FAILED

There are also undefined behavior issues left. Upcoming gcc-6 will be
much more aggressive in optimizing some of them, e.g.:
SemaTemplateVariadic.cpp:609:77: runtime error: member call on null pointer of type 'struct LocalInstantiationScope'
will lead to segfaults in clang. (
