arb crashes during display of tree

Reported by: westram Owned by: westram
Priority: critical Milestone:
Component: Library (tree) Version: SVN
Keywords: Cc:

Description (last modified by westram)

  • happens with
  • crash locations:
    • tested with big tree: NDEBUG + DEBUG version apparently crash at the same location​
    • tested with crash_arb.tree:

Observations:

  • used device seems to be corrupted when crash occurs (might be some buffer overflow?)
  • sanitizer does not report anything
  • always happens inside size detection (device is size-devive; called via AWT_canvas::instant_resize)

increasing stack-size to 40Mb fixes the problem.

Again happened with a tree calculated by fasttree:

  • a "strong" filter had been used ⇒ many species had identical filtered sequences
  • fasttree apparently inserts identical sequences into a list-style branch:
    • most degenerated branch has more than 45900 furcations
