See llvm/offload-test-suite#209 for more details
Looks like something is the scalarizer is going awry causing an assertion to be raised
# | Assertion failed: (i >= FTy->getNumParams() || FTy->getParamType(i) == Args[i]->getType()) && "Calling a function with a bad signature!", file E:\actions-runner\_work\offload-test-suite\offload-test-suite\llvm-project\llvm\lib\IR\Instructions.cpp, line 757
# | PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace, preprocessed source, and associated run script.
