## Test we report a meaningful warning for bitcode files.
## Check we try to continue dumping other files.

## Note: 'echo -e -n "\x42\x43\xc0\xde" > %t.bc.1' simply doesn't work properly on windows.
## It has an issue with writing of the 2 last bytes and emits different data instead.
## echo.exe from GnuWin32 works properly though, but using of python is a more stable way.
