Hi PRC, > Is there a particular good reason for 8-byte alignment, even if the target ARCH is 32-bit rather than 64-bit and aligment is quite a little waste of storage and runtime memory? Perhaps your platform supports 64-bit floating point, and that entails alignment requirements? Sometimes the "requirements" are performance related (e.g. Intel), sometimes they avoid SIGBUS but can be "faked" with a sigtrap to handle misalignment (such as what could be done on the DEC Alpha), sometimes they are really hard requirements such as MMX/SSE or AltiVec. Hard to say without looking at the config file for your particular platform. Sincerely, --Eljay
