The libbacktrace/Makefile.am uses a shortcut:
...

Ensure pool resources always use normal mode vector
The __pool_resource::_M_unpooled member was declared with type
std::vector, which means that the type depends on whether debug mode is
active or not. Because the non-inline definitions in

definitions, leading to undefined behaviour.
The solution is to ensure the header always uses the non-debug vector,
even when debug mode is active. To make this easier a new alias template
is defined: _GLIBCXX_STD_C::pmr::vector.
* include/std/memory_resource (__pool_resource::_M_unpooled): Use
normal mode vector, even for debug mode.
* include/std/vector [_GLIBCXX_DEBUG] (_GLIBCXX_STD_C::pmr::vector):
Define alias template for normal mode vector.

This is pretty unlikely in real code...
This is pretty unlikely in real code, but similar to Arm, the AArch64
ABI has a bug with the handling of 128-bit bit-fields, where if the
bit-field dominates the overall alignment the back-end code may end up
passing the argument correctly. This is a regression that started in
gcc-6 when the ABI support code was updated to support overaligned
types. The fix is very similar in concept to the Arm fix. 128-bit
bit-fields are fortunately extremely rare, so I'd be very surprised if
anyone has been bitten by this.

[libbacktrace] Fix strrchr segfault
Currently, when running a libbacktrace testcase t with .gnu_debuglink to
t.debug, and t.debug having a .gnu_debugaltlink to t.alt.debug, a segfault
is triggered when calling strrchr with a NULL string from
elf_find_debugfile_by_debuglink. The NULL string originates from the elf_add
called for the .gnu_debugaltlink, which uses NULL as filename argument.
Fix this by using "" as filename argument instead.
