#1 Updated by Nitin Bhat almost 2 years ago

  • Status changed from New to Implemented
  • Target version set to 6.8.1

Fix: https://charm.cs.illinois.edu/gerrit/#/c/3133/

The bug was due to a race condition where the message in the charm layer gets deleted before the deregistration in the machine layer. (as the deregistration code uses a pointer in the charm message). The fix was to store the memory region pointer in a stack object before calling the charm/converse message handler and use that for deregistration.
