hash_tree_root: pathological case in test_fixture_sanity_blocks #452

Closed mratsim closed 4 years ago

mratsim commented 4 years ago

When compiling test_fixture_sanity_blocks as a standalone and running it, I manage to block my machine for a couple minutes on what seems to be faststreams memory manager:

[Suite] Official - Sanity - Blocks  [Preset: mainnet]
  [OK] [Invalid] Previous slot block transition (prev_slot_block_transition)
  [OK] [Valid]   Same slot block transition (same_slot_block_transition)
  [OK] [Valid]   Empty block transition (empty_block_transition)
  [OK] [Valid]   Skipped Slots (skipped_slots)
