Hi,
Probably this failure is a false detection caused by a floating-point precision error in fast-math. Please ignore the mail. We'll update the test.
I apologize for the false detection.

I'd like to apologize for causing these regressions. Below
I've copied out the relevant parts from the logs. To me it
looks like _Xv is a reserved identifier.
I'll prepare a patch to fix the issue.

Code:
4651: template<_CwFixedValue _Xv, typename>
4652: struct constant_wrapper : _CwOperators
4653: {
Compiler error:
/home/tcwg-buildslave/workspace/tcwg_gnu_0/abe/builds/x86_64-pc-linux-gnu/arm-eabi/gcc-gcc.git~master-stage2/arm-eabi/libstdc++-v3/include/type_traits:4651:26:

My guess is that _Xv is a reserved name. It's not on the list
of common bad identifiers [1], but it's the only guess I have.

Thanks for the report. There is also an LLVM issue tracking this. I commented there: https://github.com/llvm/llvm-project/issues/157763#issuecomment-3273773003
The test is violating F2023 C15121 that is not properly enforced by flang semantics but that lowering now relies on.
Although we will likely improve LEN lowering which would have the side effect of working around the segfault in the specific case of 0727_0008, I think we will enforce C15121 in a manner that will reject it.
See The LLVM link for more details and suggestion on how to fix the test.

Hi,
Probably this failure is a false detection caused by the fast-math flag. The test uses NaN and very large values. Appending -fhonor-nans -fhonor-infinities resolves the failure.
Please ignore the mail. We'll update the test.
Sorry for the noise.
