Please provide a pre-processed soure file (-E option).

The output of gcc -E for this build is empty, so sure looks like the crash
is in the preprocessor.

..or maybe I'm just too dumb to invoke g++ -E properly, and the rest of the
options confuse the compiler.

Still can't reproduce it.
Please send me also output of --verbose.

Yeah, I fed that output to g++, and then it compiles just fine. But when it's
in the actual build with all the -MD -MT -MF flags, it doesn't. Those are, btw,
in case it's of any help,
-MD -MT qtbase/qmake/CMakeFiles/qmake.dir/__/src/corelib/global/qendian.cpp.o
-MF qtbase/qmake/CMakeFiles/qmake.dir/__/src/corelib/global/qendian.cpp.o.d -o

Also, you can just try the actual build, if you follow

I tried, but it fails quite fast with:

[Bug c++/97284] internal compiler error: 'global_options' are modified in local context

Right - that's the Qt bug I'm hoping to fix, but I don't get far because of the
ICE. :) The libstdc++ headers have been reorganized, so Qt's expectations that
numeric_limits is available without including <limits> are no longer valid with
GCC 11.

Good, I placed a couple of '#include <limits>' and I can reproduce it now.
Thanks for the report.

So it's caused by PCH:

$ cat qt.ii

$ cat q.ii
#pragma GCC pch_preprocess "cmake_pch.hxx.gch"
#pragma GCC push_options
#pragma GCC target ""
#pragma GCC pop_options

    options: properly compare string arguments

    Similarly to 7f967bd2a7ba156ede3fbb147e66dea5fb7137a6, we need to
    compare string with strcmp.

    gcc/ChangeLog:

            PR c++/97284
            * optc-save-gen.awk: Compare also n_target_save vars with
            strcmp.
