I believe I'm encountering this same bug with cppcheck, when building with
-flto -Os.

during GIMPLE pass: alias
lib/check64bit.h: In member function 'classInfo':
lib/check64bit.h:81:17: internal compiler error: in binds_to_current_def_p, at
symtab.cc:2497
   81 | std::string classInfo() const override {
  | ^
libbacktrace could not find executable to open
Please submit a full bug report, with preprocessed source (by using
-freport-bug).
See  for instructions.

This is with gcc 13.2.0

ext  := $(shell find externals -mindepth 1 -type d)
src  := $(shell find cli lib externals -name '*.cpp')
obj  := $(src:.cpp=.o)
CXXFLAGS := -w -Os -Ilib $(addprefix -I,$(ext)) -flto=auto
cppcheck.exe: $(obj)
x86_64-w64-mingw32-g++ -s -o $@ $(obj) -lshlwapi -flto=auto -Os -s

Place this makefile in the root of the repo, and run it.
(there is an existing one that didn't work for me, hence I named it
"cppcheck.mak")

make -f cppcheck.mak

Hope this helps!

I will try modify gcc's code to simply return instead of assert error if the
condition does not match to allow the compilation, and then check if the result
binary still woking as expected. This is only solution I came up with in the
mean time since devs are currently not focused on such small bug.

The problem occurs at final linking.

So uhh I currently have no idea on how to provide a testcase in such case.
Sorry,These compiler thing is not my profession. I just open such ticket as no
cares it before.

Exactly same problem with -Os on lto.(Seems reflect the problem in that github
issue)

The project seems only supports mingw target.
I'll get back when have more information.

The docs say this option is enabled by -Os, does using -Os reproduce the same
problem?

It would be nice to have a smaller testcase or to be able to reproduce on
x86_64-linux rather than only mingw ...
