Generates SIGBUS when compiled with optimizations for ARM CPUs. #43

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. Compile the library for ARM CPU with optimization
2. Run a simple test that deserializes JSON document
3. The process will core due to SIGBUS signal resulted from misaligned data 
access.

What is the expected output? What do you see instead?
The process should not produce SIGBUS signal and core file.

What version of the product are you using? On what operating system?
ARM CPU

Please provide any additional information below.
The cause of the misaligned data access was due to assumptions made in memory 
pool class - it has no provisions for allocated memory chunk to be aligned on 4 
byte boundary like malloc does in crt allocator rendering library useless if no 
changes made to the library for architectures sensitive to data alignment (such 
as ARM).

Revision r53 should have solved part of the problem.
Please verify if it can solve this issue. Thank you.
