wudisheng opened a new issue, #3003:
URL: https://github.com/apache/brpc/issues/3003
**Describe the bug**
We encountered an expected failure in ASAN mode when using BRPC 1.13.0. A
simple testing program reports
```
Tracer caught signal 11: addr=0x7f2cb17fd000 pc=0x7f2cb6c9c7e8
sp=0x7f2caccf0d20
==2075==LeakSanitizer has encountered a fatal error.
==2075==HINT: For debugging, try setting environment variable
LSAN_OPTIONS=verbosity=1:log_threads=1
==2075==HINT: LeakSanitizer does not work under ptrace (strace, gdb, etc)
```
Meanwhile, the same program runs well with BRPC 1.11.0 using exactly the
same compilation and invocation commands.
**To Reproduce**
I have minimized the reproduction into the following code, in BRPC
repository workspace, create the following files.
`xxx/xxx.cc`
```
#include <vector>
#include "bthread/bthread.h"
#include "butil/logging.h"
static void* Worker(void* argument) {
for (int k = 0; k < 10; ++k) {
LOG(WARNING) << "XXX: " << k;
bthread_usleep(30000);
}
return nullptr;
}
int main() {
bthread_setconcurrency(10);
std::vector<bthread_t> workers;
for (int k = 0; k < 3; ++k) {
bthread_start_background(&workers.emplace_back(), nullptr, &Worker,
nullptr);
}
for (const auto& worker : workers) {
bthread_join(worker, nullptr);
}
}
```
`xxx/BUILD`
```
cc_binary(
name = "xxx",
srcs = ["xxx.cc"],
deps = [
"//:brpc",
],
)
```
Then run with `bazel run -c fastbuild -c fastbuild --copt=-fsanitize=address
--linkopt=-fsanitize=address --linkopt=-lunwind //xxx:xxx`.
Note that when using BRPC 1.13.0 you may need to revise the `BUILD.bazel`
file which has some minor BzlMod only callsites, if you are not using BzlMod.
However, apparently this has nothing to do with the issue itself.
**Expected behavior**
Example program runs well with no ASAN or LSAN findings.
**Versions**
OS: Ubuntu 22.04
Compiler: gcc 11, gcc 12, clang 16, clang 18, clang 20
brpc: 1.13.0 (Problematic), 1.11.0 (Working)
protobuf: Unrelated (Example programs runs with the version each BRPC
release specifies)
**Additional context/screenshots**
Maybe PR #2858 (released in BRPC 1.12.0) has something to do with this ---
the LSAN messages disappeared when I hacked off the detection of
`BUTIL_USE_ASAN` macro.
