I'm encountering a compiler crash when trying to conform a C++ type to a Swift protocol using the released 5.9 compiler. Specifically, when I uncomment these lines: https://github.com/GeorgeLyon/SwiftHDL/blob/1bb24786d2771e017b6e289e3e1b428174f5e3e7/SwiftHDL/Sources/SwiftHDL/SwiftHDL.swift#L12-L14
(In that example, circt.firrtl.CircuitOp is defined in C++, and the Op protocol is defined just above in the same file). Full details of the crash are below. Anyone have any suggestions for a workaround?
On Linux: swift test -Xswiftc -cxx-interoperability-mode=default
On macOS: swift test
Linux error:
error: emit-module command failed due to signal 5 (use -v to see invocation)
error: compile command failed due to signal 11 (use -v to see invocation)
Please submit a bug report (https://swift.org/contributing/#reporting-bugs) and include the crash backtrace.
