MSVC fatal error LNK1103 when using call argument name with null character

[HertzDevil]

The following:

def foo(**opts)
end

foo("\u{0}abcdefg": 1)

gives the following error when run on Windows without --no-debug:

msvcrt.lib(guard_dispatch.obj) : fatal error LNK1103: debugging information corrupt; recompile module
Error: execution of command failed with exit status 2: "C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.38.33130\bin\Hostx64\x64\cl.exe" /nologo _main.o0.obj /FeC:\Users\nicet\AppData\Local\crystal\cache\crystal-run-test.exe.tmp.exe /link "/LIBPATH:C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.38.33130\atlmfc\lib\x64" "/LIBPATH:C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.38.33130\lib\x64" "/LIBPATH:C:\Program Files (x86)\Windows Kits\10\Lib\10.0.22621.0\ucrt\x64" "/LIBPATH:C:\Program Files (x86)\Windows Kits\10\Lib\10.0.22621.0\um\x64" /DEBUG:FULL /PDBALTPATH:%_PDB% /INCREMENTAL:NO /STACK:0x800000 /LIBPATH:C:\crystal\lib "C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.38.33130\lib\x64\msvcrt.lib"

This might be due to CodeView not supporting embedded null characters in symbol names:
