[New-bugs-announce] [issue46578] cant DEBUG os.spawnv()

[michaellongge]

New submission from michaellongge <michaellongge at 163.com>:

When i try to execute --link.exe *.obj-- on windows 11, i get one error
LIB : fatal error LNK1181: cannot open input file 'Files.obj'
It looks like a space path error
so i run [os.spawnv(link.exe)] alone try to find out where made this error.
But i cant DEBUG os.spawnv() on Pycharm.
When the cursor on os.spawnv() line then press [Step Into], cursor jump to ntpath.py (216) it's in "def basename()"  not in os.py "def spawnv()"

so this issue contain 2 parts
1.space error such as "Program Files (x86)"
2.DEBUG cant jump to right place

Here is my salmpe code.I have tried python3.8 and python3.10 both same error
```
import os

executable= 'D:\\VS2022\\VC\\Tools\\MSVC\\14.30.30705\\bin\\HostX86\\x64\\link.exe'

cmd310 = ["/LIBPATH:D:\\python310\\lib\\site-packages\\torch\\lib", "/LIBPATH:D:\\python310\\libs", "/LIBPATH:D:\\python310\\PCbuild\\amd64", "/LIBPATH:D:\\VS2019\\VC\\Tools\\MSVC\\14.29.30133\\ATLMFC\\lib\\x64", "/LIBPATH:D:\\VS2019\\VC\\Tools\\MSVC\\14.29.30133\\lib\\x64", "/LIBPATH:C:\\Program Files (x86)\\Windows Kits\\NETFXSDK\\4.8\\lib\\um\\x64", "/LIBPATH:C:\\Program Files (x86)\\Windows Kits\\10\\lib\\10.0.19041.0\\ucrt\\x64", "/LIBPATH:C:\\Program Files (x86)\\Windows Kits\\10\\lib\\10.0.19041.0\\um\\x64", "/LIBPATH:D:\\VS2019\\VC\\Tools\\MSVC\\14.29.30133\\lib\\x64", "/LIBPATH:D:\\VS2019\\VC\\Tools\\MSVC\\14.29.30133\\atlmfc\\lib\\x64", "/LIBPATH:D:\\VS2019\\VC\\Auxiliary\\VS\\lib\\x64", "/LIBPATH:C:\\Program Files (x86)\\Windows Kits\\10\\Lib\\10.0.19041.0\\ucrt\\x64", "/LIBPATH:C:\\Program Files (x86)\\Windows Kits\\10\\Lib\\10.0.19041.0\\ucrt_enclave\\x64", "/LIBPATH:C:\\Program Files (x86)\\Windows Kits\\10\\Lib\\10.0.19041.0\\um\\x64", "/LIBPATH:C:\\Program Files (x86)\\Windows Kits\\NETFXSDK\\4.8\\lib\\um\\x64", "/LIBPATH:D:\\python310\\libs", "c10.lib", "torch.lib", "torch_cpu.lib", "torch_python.lib"]
rc = os.spawnv(os.P_WAIT, executable, cmd310)
```
