What architecture is this on? Apparently l_name of VDSO in r_debug
linkmap isn't always simply an empty string. Perhaps we should ignore
entries that don't have full pathname in l_name. Does the following
fix it for you?
diff --git a/sysdeps/linux-gnu/proc.c b/sysdeps/linux-gnu/proc.c
index 9c864f3..344152e 100644

Thanks,
