3 months ago The cause was a failure to lock the mutex before calling notify_all(), which seems to be a problem in newer compilers (gcc 14, MSVC 2022 Release builds).
No re-occurance during tens of thousands of invocations of asyncappendertestcase.exe testMultiThread

3 months ago Reopening this as it seems to still be a problem on Github CI build machines. Unable to reproduce on AMD Ryzen 7 3750H in tens of thousands of invocations of asyncappendertestcase.exe testMultiThread even when using 10 as the BufferSize so the wait conditions are more frequent.

2 months ago Hello Stephen, Unrelated to this topic, when we could expect the new release ? and if it is safe to build the 'master' and ship it with software ?
Many thanks

2 months ago Releases are somewhat periodic, but I think we do have enough to do one soon.
Using master is always at your own risk
