Vicente,

I'm reworking the timed wait interface using Boost.Chrono. In this case you could use a steady clock to mean a MONOTONIC clock. Unfortunately my refactoring did use pthread_condattr_setclock to force a monotonic clock while waiting on the condition. Even if this should not be the source of the problem as it works when you don't generate the signals, I think that this will be better when available. I will need some time to make this working but I hope I could release it for boost 1.50 :(

Looking forward to that. For the moment we have a workaround, but I will keep an eye on changes in this area, so we can move back when this becomes available.

...

The demo application shows where things go right and wrong, so hopefully you should be able to reproduce the issue.

I have not understood the example completely. How do you change the time forward or backward? Could you point me where or how do you do? by hand?

Sorry, should have mentioned that. I change the time externally by hand, using the date command. When I change the time backwards (so an earlier time) the problem occurs. When I change the time forward again to a time equal to or before the time I changed the time the application continues.

...

Again, thank you for your quick response.

Thanks for reporting this and for the application example. Vicente

Thank you for your work on this. Kind regards, Johan Borkhuis
