--- Comment #1 from Patrick Marlier <patrick.marlier at gmail dot com> --- Created attachment 35936 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=35936&action=edit reduced testcase The .tm_clone_table section is not generated with LTO enabled. $ gcc -fgnu-tm -O0 -flto -c -o pr66815.o pr66815.c $ readelf -S pr66815.o | grep tm_clone_table So crt cannot notify TM clones to libitm.
