clang 消毒剂错误回调

Question

Is it possible to set some sort of a callback, which will be called when clang sanitizers find an error? I need to print some useful information, such as - test name.

PS Tests are kept/stored as XML files, not in C++, that is why stack trace won't tell me the failed test name.

Answer 1

There are __sanitizer_set_death_callback and __asan_set_error_report_callback (declared in asan_interface.h ).

Also as pointed by willir, it may be enough to just run with ASAN_OPTIONS=abort_on_error=1 . This will cause Asan to call abort on error and many unit testing frameworks can then skip failing test and continue execution.
