Crash with -g -gcodeview even with the workaround patch applied
Sorry, here's the preprocessed source with -save-temps instead of -freport-bug.
I had to compress the ii file because it was too big to be attached normally,
hopefully that's ok. The command line without the -D and -I preprocessor
options is:

Unfortunately there are no functioning debuggers on my device, at least when
trying to debug g++; LLVM's lldb and the Microsoft debugger both don't work
properly with g++, and the only debugger that does, gdb, is currently out of
commission due to a broken TLS ABI in libstdc++
I tried compiling without the following options -flto=15 -fuse-linker-plugin
-fno-strict-aliasing -fno-fat-lto-objects to see if LTO was causing the issue,
but that doesn't seem to be the case, as it crashes even without those options
set.
