Dispatch: ‘posix_memalign’, declared with attribute warn_unused_result [-Werror=unused-result]
Hi,
I seem to have problems with building latest version of Qpid Dispatch (from
master) on some systems. In particular on Ubuntu it seems to crash with the
error below which I guess is related to the DISPATCH 511 JIRA / commit
566a1a1
<https://github.com/apache/qpid-dispatch/commit/566a1a19e2c662b40aa4477421bddb51e4e7310c>.
Interesting enough, it seems to work fine on CentOS 7.
Is this a bug in the dispatch code? Or do I need to use different version
of some libraries?
Thansk & Regards
Jakub

Thanks Ted. My build seems to work fine again now after your fix.

Jakub,
This is a bug in the DISPATCH-511 update. I'll get it fixed.
