Hello, I upgrade the gcc in my setup from 10.2 to 10.5 to the latest commit. After that I build an application with the -fsanitize=leak option. The execution of the application stops immediatly after start with the following error: CHECK failed: ../../../../src/libsanitizer/lsan/lsan_interceptors.cpp:53 ((!lsan_init_is_running)) != (0) (0, 0) I did some research and found following Issue discussion on Github: https://github.com/magma/magma/issues/15279 There is as well a solution describe to overwrite __lsan_init() call with an own, empty, implementation. This is not feasible for me, because I need to check the applicaitons with the fsanitizer=leak. There is as well a bug ticket of the error at the ubuntu launch pad: https://bugs.launchpad.net/ubuntu/+source/gcc-defaults/+bug/2038386 The solutions to upgrade to gcc 11 or downgrade to gcc 10.2 are not feasible for me. I did as well research on the commits from gcc to find a solution, but could not find a patch, that points directly to that Issue. In the bug ticket from Ubuntu they say that the: "dlopen- specific allocator was reimplemented". Does anyone had experience with that Issue and knows a solution? Thanks in advance BR Michael
