            Bug ID: 29929
           Summary: gdb looks for "target:" file on the target
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: remote
          Assignee: unassigned at sourceware dot org
          Reporter: tromey at sourceware dot org
  Target Milestone: ---

A simple way to reproduce this bug is to:
$ gdb /bin/ls
(gdb) target remote | gdbserver - /bin/ls
(gdb) cont

If you examine the output, you'll see something like:

Reading target:/usr/lib/debug/lib64//libcap.so.2.48-2.48-4.fc36.x86_64.debug
from remote target...

That "target:" is leaking through to the remote, which is
nonsensical.

It comes from this code in find_separate_debug_file:

          debugfile =3D target_prefix ? "target:" : "";
          debugfile +=3D gdb_sysroot;
          debugfile +=3D debugdir;

(top-gdb) p gdb_sysroot
$18 =3D "target:"
