Description Ted Bagg 2010-08-28 21:36:45 UTC 
This was reported as Bug 397 and was fixed in v3.0.0, I believe.  But the fix has not been applied to v2 as of 2.0.9, the current stable branch at the time of this report.  My company must use v2 for the moment as we need compatibility with Mac clients.

Moreover, fix supplied in 3.0.0 is inefficient on an ARM because memcpy() is not inlined there in gcc -g -O2.  I've attached a better fix below for 2.0.9 which should be no slower on most other architectures.  Companion patches will be supplied in a related entry for v3, where the corresponding revision is an enhancement rather than a repair.

Downgrading severity as it affects specific platforms.
Comment 2 Amar Tumballi 2010-10-05 05:54:04 UTC 
We will work on only x86_* arch for the 3.1.0, will take it in 3.1.x version
Comment 3 Amar Tumballi 2011-01-21 07:50:34 UTC 
With the current codebase, this bug is invalid, as we have fixed the issues with architecture dependent code. Please use 3.1.x version.
