            Bug ID: 92933
           Summary: [coroutines] compiler ICE compiling coroutine with
                    try/catch
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org

Example program

Compiling the attached program crashes the compiler with a segmentation fault
when compiling with gcc coroutines branch.

See https://godbolt.org/z/kCNVfQ

This has a simple coroutine that looks like:

struct some_error {};

task foo() {
    try {
        co_return;
    } catch (some_error) {
    }
}

Compilation with '-std=c++2a' crashes with the following error:

<source>: In function 'task foo()':
<source>:64:1: internal compiler error: Segmentation fault
   64 | }
      | ^

Removing the try/catch compiles fine.
Replacing the catch(some_error) with catch(...) compiles fine.
