Hello, I was working on a script and running into problems with passing an argument with a wildcard with the C:\WINDOWS\System32 path. Observe: --- C:\>more test.rb puts ARGV C:\>test.rb C:\ruby\*.txt C:/ruby/ChangeLog.txt C:/ruby/LICENSE.txt C:/ruby/ReleaseNotes.txt C:\>test.rb C:\WINDOWS\system32\runonce.exe C:\WINDOWS\system32\runonce.exe C:\>test.rb C:\WINDOWS\system32\runonce.ex* [BUG] cross-thread violation on rb_gc() ruby 1.8.5 (2006-08-25) [i386-mswin32] This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information. C:\>ruby -v ruby 1.8.5 (2006-08-25) [i386-mswin32] --- I haven't been able to figure out or find a workaround (besides just knowing all the filenames) or fix. I thought Windows takes care of the wildcard, generating the argument list. I don't know how that would help, but earlier today it made sense to me that it meant something. And this happens even if ARGV is never referenced (e.g. an empty test.rb does the same thing), so it looks like the violation happens even before the script is interpreted. And, yes, I'm logged in with an administrator account (Windows users usually are, aren't they?). Anyone have any insight? Or is this just one of those things (one of those things about working with Windows)?
