The error return values from FSMakeFSSpec() and FD_FSSpecCreateCFURL() may be helpful in diagnosing the crash.

Alternatively, you could do without gDesktopFileSpec, as in the code below.

'--------
include "Util_FileDirectory.incl"
dim as CFURLRef  fileUrl, folderUrl
dim as OSStatus  err

err = fn FD_SpecialDirectoryCreateCFURL( _kUserDomain, _kDesktopFolderType, @folderUrl )
if ( err ) then stop "FD_SpecialDirectoryCreateCFURL error " + str$( err ) : end
err = fn FD_PathCreateCFURL( @"BoardScreenshot.jpg", folderUrl, @fileUrl )
CFRelease( folderUrl )
if ( err ) then stop "FD_PathCreateCFURL error " + str$( err ) : end
//
//.. your code that uses fileUrl...
//
CFRelease( fileUrl )
