            Bug ID: 26003
           Summary: infinite loop loading symbols from separate debug
                    objfile
           Product: gdb
           Version: 9.1
            Status: NEW
          Severity: normal
          Priority: P2
         Component: symtab
          Assignee: unassigned at sourceware dot org
          Reporter: brobecker at gnat dot com
  Target Milestone: ---

This is to record an issue which was fixed in master on Apr 10th, 2020:
https://sourceware.org/pipermail/gdb-patches/2020-April/167305.html

<<
Sometimes, get_msymbol_address can cause infinite recursion, leading
to a crash.  This was reported previously here:

https://sourceware.org/pipermail/gdb-patches/2019-November/162154.html

A user on irc reported this as well, and with his help and the help of
a friend of his, we found that the problem occurred because, when
reloading a separate debug objfile, the objfile would lose the
OBJF_MAINLINE flag.  This would cause some symbols from this separate
debug objfile to be marked "maybe_copied" -- but then
get_msymbol_address could find the same symbol and fail as reported.
