> Anyway I still think that we are too fast with toolchain upgrade, but I'm more conservative. Do we have a significant gain in optimisation with new compiler? Or what is the rush here? The new toolchain adds more static analyzer on compile stage, which will helpful for code quality: https://gcc.gnu.org/gcc-11/changes.html  For example: ``` if (focus != NULL) { nxipc_client_disconnect(focus->send_proxy); nxipc_sub_disconnect(focus->receive_proxy); free((void*)focus->name); free((void*)focus); pthread_mutex_destroy(&focus->mutex); <-- use-after-free } ``` build will break on gcc-11.3 ([-Werror=use-after-free]) ``` ../common/src/client/app_focus_c.c: In function 'app_focus_release': ../common/src/client/app_focus_c.c:157:9: error: pointer 'handle' used after 'free' [-Werror=use-after-free] 157 | pthread_mutex_destroy(&focus->mutex); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ../common/src/client/app_focus_c.c:156:9: note: call to 'free' here 156 | free((void*)focus); | ^~~~~~~~~~~~~~~~~~ ``` -- This is an automated message from the Apache Git Service.
