            Bug ID: 31152
           Summary: Formalise unintened functionality in version 9.1
           Product: gdb
           Version: 14.1
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P2
         Component: gdb
          Assignee: unassigned at sourceware dot org

  Target Milestone: ---

Most of the time (approximately 95%) I use a gdb binary provided by the Lin=
ux
distribution I am using. The remainder of the time, I cross compile a source
release for an obscure processor, in order to debug on =E2=80=9Cbare metal=
=E2=80=9D
(re-purposing old tech so all I have to start with is a Linux kernel and a
terminal of some kind).

The first time I did this I used release 9.1 and cross compiling a static
executable gave me what I needed. This time (after cross compiling glib etc=
) I
tried the same with version 14.1 and the box restarted indicating a kernel
error. I rebuilt 9.1 and started to debug 14.1 and found it was trying to e=
xec
iconv. A quick hack and it compiled with the dummy iconv used for a win32 b=
uild
only to have a segment trap because the ifdef path for linux used a pointer=
 set
up through the exec iconv path.

I have a workaround because I can use version 9.1 (possibly others, I have =
not
checked) until GCC adopts a version of dwarf this version does not understa=
nd,
so I believe this is low priority.

I wish to request an enhancement of a configuration option for =E2=80=9Cbar=
e metal=E2=80=9D
which errors at some point (even compile or link) if more than a linux kern=
el
is required to run the executable.
