Debugging fails for statically linked programs

[sth]

Debugging a statically linked program fails:

$ gcc -gdwarf -no-pie -static -o tests/hello tests/hello.c
$ ups/ups tests/hello
Can't find shared library information in ELF executable ./blah (no `.dynamic' section)
Hello world
Fatal internal error: ao_read_text_from_process with no proc (aborting) ...
Dumping core ... Aborted (core dumped)

ptrace_init_pid is called with a valid pid at some point, but in ao_read_text_from_process
ip->ip_pid is zero. There are several placed where ip_pid might get reset to zero.

There seems to be a historical issue with statically linked programs:

ups/ups/ao_elflib.c
