(gdb) continue^M Continuing.^M ^M Breakpoint 2, 0x00007ffff7d4405e in vfork () from /lib64/libc.so.6^M (gdb) PASS: gdb.base/step-over-syscall.exp: vfork: displaced=off: \ continue to vfork (1st time) ... but with glibc debuginfo installed I get instead: ... (gdb) continue^M Continuing.^M ^M Breakpoint 2, 0x00007ffff7d4405e in __libc_vfork () at \ ../sysdeps/unix/sysv/linux/x86_64/vfork.S:44^M 44 ENTRY (__vfork)^M (gdb) FAIL: gdb.base/step-over-syscall.exp: vfork: displaced=off: \ continue to vfork (1st time) ... The FAIL is due to a mismatch with regexp: ... "Breakpoint \[0-9\]+, (.* in |__libc_|)$syscall \\(\\).*" ... because it cannot match both ".* in " and the __libc_ prefix. Fix this by using instead the regexp: ... "Breakpoint \[0-9\]+, (.* in )?(__libc_)?$syscall \\(\\).*" ...
