raco pollen hello.txt.pp crash on Win64 #72

Brand new to Racket and Pollen; am following Quick Tour tutorial and at section 2.3 running raco pollen hello.txt.pp crashes with a popup dialog: "Racket application has stopped working. A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available."

...ahhh, figured it out. My hello world file is in a SUBST drive (B:\: => C:\Users\me\Dropbox).

Closing because this is probably an upstream problem with Racket/Windows and not Pollen.

For the record, SUBST might be a red herring, with the root cause being use of Windows "mount NTFS volume in empty folder" feature

I’ll take a look. Might be a Pollen problem but it looks like the Racket normalize-path function isn’t coping with the remapped drive as it ought to.

Sorry, but I have no idea, and my Windows skills are not deep enough to reproduce the problem.

For anyone who might investigate further the recipe to reproduce is:

Find a drive with no open files and nothing important on it (a USB stick will do).
Remove it's drive letter:
- Open Disk Management (Start >>Run >> diskmgmt.msc)
- Select volume >> R-click >> Change Drive Letter and Paths >> remove letter >> OK
- Select same volume >> R-click >> Change Drive Letter and Paths >> [Add] >> Mount in following empty folder >> select folder >> OK
Copy pollen project to that path, e.g. D:\mount\usb_x, and then run raco pollen hello.txt.pp

Update: don't forget to reverse process to get your device back at the old drive letter.
