Re: [Live-devel] segfault in
DelayQueue::removeEntry()should the sanity check, at the beginning
of the function, be patched in the following  way?



- if (entry == NULL || entry->fNext == NULL) return;


+ if (entry == NULL || entry->fNext == NULL || entry->fPrev == NULL) return;


In principle, this shouldn't be necessary, as it should never be
the case that "entry->fNext" is non-NULL, but
"entry->fPrev" is NULL.


So, I don't understand how your error could have occurred. 
I hope you're not doing something dumb like trying to access a queue
from multiple threads?


Puzzling...

yes, you're right :-( . I used a thread-unsafe operation (not so dumb, but unsafe)
