Hi Kent,

  :)
  No fear! I am interested in solving the problem -- regardless where
  it is -- even it sits directly in front of my monitor and keyboard :)

  That's why they are assumptions .. not facts ... :)))

  Proof ?

  No...that would mean, that evberyone using Linux would have the
  same memory mapping.

  On a logical view that as faulty as mine assumptions.

  On a base of experience that may be true...or not...

  Yes...Gimp is a completly different thing and program...I know.

  We cannot fix this if we only know that it is "something" :)

  If I use trace points and step over it: it hangs not.
  Else it hangs.

  Totally reproduceable...

  No reason to try it ... from my point of view...


  Keep Hacking!
