<pre>Consider:
$ cat t.cpp
int main() {
#pragma clang __debug assert
}
$ clang -c t.cpp
This is an assertion!
UNREACHABLE executed at ..\tools\clang\lib\Lex\Pragma.cpp:871!
clang.exe: error: clang frontend command failed with exit code 3 (use -v to see
invocation)
'abort' gives exit code 3 on Windows, making this code fail:
// If result status is < 0, then the driver command signalled an error.
// If result status is 70, then the driver command reported a fatal error.
// In these cases, generate additional diagnostic information if possible.
if (CommandRes < 0 || CommandRes == 70) {
TheDriver.generateCompilationDiagnostics(*C, FailingCommand);
break;
