[Bug tui/11623] New: GDB assertion in TUI mode, with ARM elf loaded application

[eblotml at free dot fr]

In TUI mode, when [Ctrl]-X, 2 is pressed from the single source window mode, GDB core dumps with the 
following trace message:
 
This GDB was configured as "--host=x86_64-apple-darwin10.3.0 --target=arm-eabi".
Reading symbols from /Users/eblot/Sources/blatann.elf...done.

(gdb) gdbarch.c:1455: internal-error: gdbarch_addr_bit: Assertion `gdbarch != NULL' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.

The problem occurs with 7.0.1 and 7.1 builds

The same problem is observed in the reverse action order:

1. Start up arm-eabi-gdbtui without a file to debug.
2. Successfully switch to double window mode with [Ctrl]-X, 2
3. Load the application to debug: file blatann.elf
    -> same crash occurs, with the same message

The same issue can be reproduced even more easily: 
 * "layout asm" seems to trigger the same issue.
 * "layout src" does not trigger the issue.

A similar bug report for Debian exists here:

[Bug gdb/11623] GDB assertion while attempting to show the ASM source of an ARM-EABI application

Fixing the description as the issue is not related to TUI mode, but to ASM (ELF parsing ?)
