Steps:

1. Download the attached ELF: zephyr.zip
2. Open GDB using: arm-zephyr-eabi-gdb.exe zephyr.elf
3. Send the following command: disas arch_tls_stack_setup

Result: GDB closes immediately with exit code 3. No other error messages are printed.

Expected: ARM GNU Toolchain 13.2.Rel1 disassembles the function correctly

Zephyr SDK: Tested with both 0.17.0 and 0.18.0-alpha2
Platform: Windows 10

Additional information

The provided ELF was built with Zephyr hello_world example for Board: NXP LPCXpresso55S69 (CPU0)

The issue occurs constantly with cortex-debug, and is probably related to #609, but the cause is clearly GDB here.
As mentioned above, using a newer GDB from the ARM toolchain fixes this issue.
