Panic When Using Glob

[nsmryan]

I got a panic when running scc on the command line in Windows 10.

The command was:

scc */*.cpp 

when run on a directory with no sub-directories (I forgot which directory I was in and ran this by accident). The same command works fine when there are sub-directories to enter.

The error message was:

panic: runtime error: invalid memory address or nil pointer dereference
[signal 0xc0000005 code=0x0 addr=0x10 pc=0x52ad92]

goroutine 4 [running]:
github.com/boyter/scc/processor.walkDirectoryParallel(0x1140a080, 0x7, 0x11482140)

Not a big issue, since the glob doesn't match any files anyway, but an error message would be nicer than a panic.

Fix sitting in PR #78 which I will merge once it ensures the build works as expected.

Thanks for reporting this. I could only trigger it on Windows but it is now resolved,

C:\Users\bboyter\Documents\Go\src\github.com\boyter\scc>go run main.go */*.cpp
ERROR 2019-05-06T22:18:07Z: GetFileAttributesEx *\*.cpp: The filename, directory name, or volume label syntax is incorrect.exit status 1

Merged into master. Will be rolled into the next release. If you need a fix now then please build from master.

Once again thanks for reporting this!
