I put this up here because it wasted me untold hours figuring it out.
Logitech Quick Camera 9.X crashes cygwin......AAAAAAaaarg!
Does this look familiar:
*** fatal error - couldn't allocate heap, Win32 error 487
Sorry, the only solution I have at this point is to uninstall the Logitech Quck Camera driver.
I read that the earlier driver worked with cygwin. I believe this to be a Logitech bug at this point and I can't use windows without cygwin. So, Quick Camera has been moved to /dev/null.
Update: Seems people out there are still having this problem. I have run into another problem: ruby is slow under cygwin (painful in my old laptop). I may give coLinux a try. It probably works with quick cam and ruby should fly...
Update: As Kevin Szabo points out in the comments to this post: "This may be a problem with a conflict with LVPrcSrv.exe". He provided a link to the thread here.
