#308 closed task (fixed)

check that foreign callback returns take place in the correct order

Reported by: felix winkelmann Owned by: felix winkelmann
Priority: minor Milestone:
Component: core libraries Version: 4.5.x
Keywords: foreign callback Cc:
Estimated difficulty:


Multiple threads or use of continuations may result in returns from foreign callbacks happen not in the required order. By keeping a stack of addresses (for example from a local variable in the callback entry) this could be checked by the runtime system.

Resolution: fixed
Status: newclosed

Currently only a check for returning twice from the same callback has been implemented by setting a flag inside the callback return-continuation closure, which should handle the case of code doing funny things with continuations.
