Please could you add the compiler, boost version and a small test that shows the backtrace?

[viboes]

Could you see if the patch in #9569 fix the crash?

crash do come very rarely. We have 2 writer threads and multiple reader

[anonymous]

My Boost version is 1.46.1..

[viboes]

Have you applied the patch?

[anonymous]

As crash is not reproducible so we cant be sure about the patch.

I read the issue fixed in the patch, As per my understanding, This patch do fix the upgrade lock issue (thread don't get upgrade lock if some read lock is already there). I am not sure, can this problem cause crash? Error code is EINVAL not EDEAD in my scenario.

Please correct me if my understanding is wrong.

[viboes]

Sorry, I didn't see that you were on linux. I expect that you applied the patch at #5516 ;-)

Could you show the code?

[viboes]

Yes, as there is a throw.

I will move it as duplicated of #5516.
