NFC: Add LSAN leak suppression to ASAN pipeline#7503
Merged
Conversation
address-sanitizer reports a leak coming from the dynamic shared library loading code, though dlopen() is paired with dlclose(). This leak doesn't manifest on main yet because dxc adds dxcompiler directly to target_link_libraries (which it shouldn't have to), and dxil is loaded within that library. A PR to remove dxil loading from dxcompiler exposes the leak when dxc loads dxil dynamically. This change adds a suppressions file for LSAN to suppress the leak in the loader code that happens under call_init. To make this work, it must also change the Release build to RelWithDebInfo so symbols are present, which are required to resolve the function name we match in the suppressions file.
