When compiling on ARM, the following error message occurs: cast from 'char*' to 'uint64_t* {aka long long unsigned int*}' increases required alignment of target type [-Werror=cast-align] (or similar) in several locations.
Upstream bug: https://issues.apache.org/jira/browse/QPID-5401
Fixed in r.1550446
My bad, this fix is an upstream 0.26 branch fix.
