[clang++-19][regression] "error: type constraint differs in template redeclaration"

[mpusz]

I get the following error while compiling on clang-19:

[build] ../../src/core/include/mp-units/framework/quantity_point.h:111:26: error: type constraint differs in template redeclaration
[build]   111 | MP_UNITS_EXPORT template<QuantitySpec auto QS>
[build]       |                          ^
[build] ../../src/core/include/mp-units/framework/quantity_point_concepts.h:35:26: note: previous template declaration is here
[build]    35 | MP_UNITS_EXPORT template<QuantitySpec auto QS>
[build]       |                          ^

Here are the offending declarations:

• https://github.com/mpusz/mp-units/blob/5f2cb780376592b967869544a0178e09a64ddfda/src/core/include/mp-units/framework/quantity_point.h#L111-L114
• https://github.com/mpusz/mp-units/blob/5f2cb780376592b967869544a0178e09a64ddfda/src/core/include/mp-units/framework/quantity_point_concepts.h#L35-L36

The same code works fine on clang-17, clang-18, gcc-13, and gcc-14.

A repro can be found here: https://godbolt.org/z/6brEd3de6. It also fails on "clang (trunk)," but it works fine on the other compilers mentioned.

I came to open an issue exactly about this with llvm-19.1.0 via homebrew on Apple M1 Pro CPU.
llvm-18.1.8 via homebrew and apple-clang 16 successfully compiles.

Looks like this started in clang-19: https://godbolt.org/z/oxPf3oWjM

I would like a reduction to understand what is going on better though.

[Endilll]

Confirmed on 19 and trunk.
This was very tricky to reduce. (Partial) reduction that I have works intermittently, failing to compile in 10-20% runs, and compiling successfully otherwise. So it's advised to hit the recompilation button 10 times before considering the example as working.
Another notable thing is that seemingly innocuous changes like removing an unused lambda can trigger SIGSEGV without stack instead of the diagnostic.

Note several declarations between quantity_point declarations at the end. It seems that constant evaluations and template argument deductions triggered by them bring Clang into inconsistent state.
Reduced by me and C-Reduce (https://godbolt.org/z/jbEbfrexP):

CC @mizvekov because I saw several TTPs are at play (where the situation could be horrible)

[Endilll]

Somewhat surprisingly, when I locally ran Clang 19.1 binary that CE uses against the reduction, I got a crash:

PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace, preprocessed source, and associated run script.
