hello-world.elf ; a broken firmware for the MSP430F1611 that I fail to debug

Thanks for the quick reply. I attached the binary in question, a simple
application that flashes on an MSP430F1611 MCU and outputs "Hello world" via
UART using RIOT. (Specifically,
https://github.com/maribu/RIOT/tree/tmp/examples/hello-world is the
corresponding code and can be generated by `make BOARD=olimex-msp430h1611`.)

Note that this firmware isn't functional; I'm in the process of figuring out
why the firmware generated with my new toolchain doesn't work, while it does
work with an older toolchain.

Here is the requested info:

(gdb) p *bmsym.minsym
$2 = {<general_symbol_info> = {m_name = 0x7ffff6ebed34 "BCSCTL1", m_value =
{ivalue = 87, block = 0x57, 
      bytes = 0x57 <error: Cannot access memory at address 0x57>, address = 87,
common_block = 0x57, chain = 0x57}, 
    language_specific = {obstack = 0x0, demangled_name = 0x0}, m_language =
language_auto, ada_mangled = 0, m_section = 0}, 
  m_size = 0, filename = 0x7ffff6bbb500 "irq.c", m_type = mst_abs,
created_by_gdb = 0, m_target_flag_1 = 0, 
  m_target_flag_2 = 0, m_has_size = 1, maybe_copied = 0, name_set = 1,
hash_next = 0x0, demangled_hash_next = 0x0}
