iterator invalidated{erase: opaque

See also

I had multiple encounters with STL iterator invalidation, esp. after erase().

  • sometimes I get correct result
  • sometimes I get segfault
  • sometimes I get incorrect result

Opaque i.e. no obvious clues, so no keyword to google

Luckily my code was 20-lines

Luckily i could reproduce it once a while.

This is another example of tough bugs to hunt down.
