17864	Apply patch to GDB to prevent it from crashing during rust tests	Douglas R. Reno	Douglas R. Reno	"While I've been working on updating rustc to 1.68.1 (#17860), I've noticed an apparent bug in gdb that causes gdb to crash with an internal error during rust's tests...

---

Breakpoint 22, destructured_fn_argument::multiple_arguments (../../gdb/frame.c:2457: internal-error: inside_main_func: Assertion `block != nullptr' failed.

A problem internal to GDB has been detected,

further debugging may prove unreliable.

Quit this debugging session? (y or n) [answered Y; input not from terminal]

In another test, gdb refuses to even run on the program and crashes immediately with a SIGABRT.

The following tests fail:

{{{
failures:
    [debuginfo-gdb] tests/debuginfo/destructured-fn-argument.rs
    [debuginfo-gdb] tests/debuginfo/function-arguments.rs

There is a patch upstream to fix these crashes in GDB: [https://sourceware.org/git/?p=binutils-gdb.git;a=patch;h=562403d4f5483e0787219fdb88da72c707c8d7f6]"	enhancement	closed	normal	12.0	BOOK	git	medium	fixed
