================
Comment at: compiler-rt/lib/sanitizer_common/sanitizer_linux_libcdep.cc:208
+  if (CHECK_GET_TLS_STATIC_INFO_VERSION &&
+      !dlvsym(RTLD_NEXT, "glob", "GLIBC_2.27"))
+    CallGetTls<GetTlsStaticInfoRegparmCall>(get_tls_static_info_ptr,
----------------
This breaks lsan:

```
==211269==Sanitizer CHECK failed: compiler-rt/lib/lsan/lsan_interceptors.cc:54 ((!lsan_init_is_running)) != (0) (0, 0)
```

dlvsym calls malloc when lsan is not initialized
