new testcase
Here's a better testcase:
gcc -fuse-ld=bfd -shared tsan_rtl.o tsan_interceptors.o tsan_rtl_amd64.o
vs.
gcc -fuse-ld=gold -shared tsan_rtl.o tsan_interceptors.o tsan_rtl_amd64.o
Look at the disassembly of function _ZN6__tsan10InitializeEPNS_11ThreadStateE.
bfd:
cur_thread()->ignore_interceptors++;
2d4a3: 48 03 05 ce 67 25 00 add 0x2567ce(%rip),%rax #
283c78 <.got+0x1780>
gold:
cur_thread()->ignore_interceptors++;
