Arduino IDE Linking error when Win Username has a space

[jlcook83]

I am experiencing an issue when the Arduino IDE is compiling for a Multi-4-in-1 board, and I am logged in with a windows username that contains a space.

During the linking stage an error is thrown right after successful execution of: do_version.bat

The error is thrown in the middle of my windows user name, (again, contains a space).

i.e User is 'My Name',
The error thrown is: 'C:\Users\My' is not recognized as an internal or external command

When I run under a Windows user that doesn't contain a space, the compile completes successfully. I believe this is related to something in the linking process.

Note: I can compile code when other than a 'Multi-4-in-1 ' AVR board is selected (i.e compile for Arduino Mini works fine with username containing a space.)

This is a known problem with the Arduino IDE:
arduino/arduino-builder#316

Which is caused by an underlying issue in Golang:
golang/go#17149

The only way to work around the problem is to move the Multi source folder to a path without spaces in it, e.g. C:\Temp\Multi.

Edit: The reason it works for other boards is that we do some magic in post-build scripts, which is where this bug is encountered. Other boards (i.e. the Mini) don't have post-build scripts, so don't trigger the bug.
