When using glibc-2.34, we now see messages related to the loading of the thread library for non-thread programs. E.g. for the test case, gdb.base/execl-update-breakpoints.exp, we will see the following when starting the program: (gdb) break -qualified main Breakpoint 1 at 0x100118c: file /ironwood1/sourceware-git/f34-2-glibc244_fix/bld/../../worktree-glibc244_fix/gdb/testsuite/gdb.base/execl-update-breakpoints.c, line 34. (gdb) run Starting program: [...]/execl-update-breakpoints1 [Thread debugging using libthread_db enabled] Using host libthread_db library "/lib64/libthread_db.so.1". The two lines of output related to libthread_db are new; we didn't see these in the past. This is a side effect of libc now containing the pthread API - we can no longer tell whether the program is multi-threaded by simply looking for libpthread.so. That said, I think that we now want to load libthread_db anyway since it's used to resolve TLS variables; i.e. we need it for correctly determining the value of errno. This commit adds the necessary regular expressions to match this (optional) additional output in the two tests which were failing without it. gdb/testsuite/ChangeLog: * gdb.base/execl-update-breakpoints.exp: Add regular expression for optionally matching output related to libthread_db. * gdb.base/fork-print-inferior-events.exp: Likewise.
