Bug ID: 64013
Summary: [5 Regression] libsanitizer fails to build
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: sanitizer
Assignee: unassigned at gcc dot gnu.org
Reporter: rguenth at gcc dot gnu.org

[35101s] I: Program returns random data in a function
[35101s] E: gcc5 no-return-in-nonvoid-function
../../../../libsanitizer/sanitizer_common/sanitizer_linux.cc:295
bool FileExists(const char *filename) {
#if SANITIZER_USES_CANONICAL_LINUX_SYSCALLS
struct stat st;
if (internal_syscall(SYSCALL(newfstatat), AT_FDCWD, filename, &st, 0))
return false;
#else
struct stat st;
if (internal_stat(filename, &st))
return false;
// Sanity check: filename is a regular file.
return S_ISREG(st.st_mode);
#endif
}
the SANITIZER_USES_CANONICAL_LINUX_SYSCALLS misses a return.
