Severity: normal
--- Please enter the report below this line. ---
GCC says that -pie or -shared is needed to use -fsanitize=thread, but that is
not enough on amd64:
$ /usr/bin/gcc-4.8 -fsanitize=thread test.c -pie
/usr/bin/ld.bfd.real: /tmp/ccBEgPXP.o: relocation R_X86_64_PC32 against
undefined symbol `__tsan_func_entry' can not be used when making a shared
object; recompile with -fPIC
/usr/bin/ld.bfd.real: final link failed: Bad value
collect2: error: ld returned 1 exit status
-fPIC is needed too:
$ /usr/bin/gcc-4.8 -fsanitize=thread test.c -pie -fPIC
