ASAN: Support coroutine context switching and stack tracing (#4153) For coroutine, we should use `__sanitizer_start_switch_fiber` which similar to`VALGRIND_STACK_REGISTER`, see https://github.com/google/sanitizers/issues/189#issuecomment-1346243598 for details. If not fix this, asan will output warning: ``` ==72269==WARNING: ASan is ignoring requested __asan_handle_no_return: stack type: default top: 0x00016f638000; bottom 0x000106bec000; size: 0x000068a4c000 (1755627520) False positive error reports may follow For details see https://github.com/google/sanitizers/issues/189 ``` It will cause asan failed to get the stack, see `research/st/asan-switch.cpp` for example: ``` ==71611==ERROR: AddressSanitizer: heap-buffer-overflow on address 0x000103600733 at pc 0x0001009d3d7c bp 0x000100b4bd40 sp 0x000100b4bd38 WRITE of size 1 at 0x000103600733 thread T0 #0 0x1009d3d78 in foo(void) asan-switch.cpp:13 ``` After fix this issue, it should provide the full stack when crashing: ``` ==73437==ERROR: AddressSanitizer: heap-buffer-overflow on address 0x000103300733 at pc 0x000100693d7c bp 0x00016f76f550 sp 0x00016f76f548 WRITE of size 1 at 0x000103300733 thread T0 #0 0x100693d78 in foo(void) asan-switch.cpp:13 #1 0x100693df4 in main asan-switch.cpp:23 #2 0x195aa20dc (<unknown module>) ``` For primordial coroutine, if not set the stack by `st_set_primordial_stack`, then the stack is NULL and asan can't get the stack tracing. Note that it's optional and only make it fail to display the stack information, no other errors. --- Co-authored-by: john <hondaxiao@tencent.com> 2024-08-22 09:12:39 +00:00			`asan-switch`
