Paths not trimmed throws exception when path starts with space

[hype8912]

Below is the command line I used and accidentally left a space in the beginning when I was trying to call a file directly. You can duplicate it with any file type by leaving a space at the beginning of the quotes.

Environment:

• Windows 10.0.19045 Pro Build 19045
• 48 GB RAM
• Release is 1.6.0

validator -quiet " C:\Temp\dotnet_examples\DotNet Examples\BenchmarkRunner\TestObjects\HashFile_Small.xml"

Here's the output:

panic: runtime error: invalid memory address or nil pointer dereference
[signal 0xc0000005 code=0x0 addr=0x28 pc=0xa075a5]

If you remove the space at the beginning of the quoted path it runs correctly. Not a major issue since there is a workaround.
