This looks like the locking code does not work outside of libc: /home/bmg/install/compilers/i686-gnu/lib/gcc/i686-glibc-gnu/11.1.1/../../../../i686-glibc-gnu/bin/ld: /home/bmg/build/glibcs/i686-gnu/glibc/malloc/libc_malloc_debug_pic.a(malloc-debug.os): in function `__malloc_info': /home/bmg/src/glibc/malloc/malloc.c:5670: undefined reference to `__gsync_wait' /home/bmg/install/compilers/i686-gnu/lib/gcc/i686-glibc-gnu/11.1.1/../../../../i686-glibc-gnu/bin/ld: /home/bmg/src/glibc/malloc/malloc.c:5756: undefined reference to `__gsync_wake' I'm not entirely sure how this is supposed to work. Clearly the libc locks work outside of libc for other DSOs, and libc_malloc_debug is built with -DMODULE_NAME=libc_malloc_debug, so it should be recognized as outside of libc. Thanks, Florian
