[LLVMdev] Why buildbot sanitizer-ppc64-linux1 blames r239459?

I'm trying to understand why the buildbot sanitizer-ppc64-linux1 fails due
to my latest patch. It was in llvm::GlobalValue while the reported failure
is:
strcspn-2.c.tmp:
/home/buildbots/sanitizerslave1/sanitizer-ppc64-1/build/llvm/projects/compiler-rt/test/asan/TestCases/strcspn-2.c:17:
int main(int, char **): Assertion `r == sizeof(s1) - 1' failed.
where strcspn-2.c (below) tests the strcspn function and does not use any
header from LLVM, completely unrelated to GlobalValue.
Yet, the buildbot reports that r239457 and r239458 were built OK and the
failure started in my patch r239459:
http://lab.llvm.org:8011/builders/sanitizer-ppc64-linux1
Why is the builbot blaiming r239459? is this a buildbot bug?

int main(int argc, char **argv) {
size_t r;
char s1[] = "ab";
char s2[] = {'c', 'd'};
char s3 = 0;
r = strcspn(s1, s2);
// CHECK:'s{{[2|3]}}' <== Memory access at offset {{[0-9]+ .*}}flows this
variable
assert(r == sizeof(s1) - 1);
return 0;
}
