            Bug ID: 41617
           Summary: clang-cl 8.0.0 crashes with OpenMP construct
           Product: OpenMP
           Version: unspecified
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: normal
          Priority: P
         Component: Runtime Library
          Assignee: unassignedbugs at nondot.org

Preprocessed source and associated run script

clang-cl crashes with the following code:

void f()
{
    int e;
    auto g = [e] (auto)  // a concrete parameter type (like 'int') instead of
'auto' is OK
    {
        #pragma omp critical
        e;
    };

    #pragma omp parallel for
    for (int i = 0; i < 42; ++i)
        g(i);
}

Please note that it does compile with a concrete parameter type for the lambda
instead of the generic auto.

Compiled with "-Xclang -fopenmp /std:c++latest" in VS2019 using LLVM_v142
toolset from llvm-utils.
The error report is:

The code is a simplified stripped down version of real production code. I know
that it does effectively nothing, I just wanted it to be as simple as possible.
It should compile nonetheless.

It also does not compile on godbolt's clang (https://godbolt.org/z/zi0aVI).
