New issue 360 by [email protected]: Alignment check on in configure.ac is
broken and results in addition memcpy()s
http://code.google.com/p/memcached/issues/detail?id=360
What steps will reproduce the problem?
1. Build memcached
2. NEED_ALIGN is always set to 1
3. The memcached code does an unneeded memmove
What is the expected output? What do you see instead?
NEED_ALIGN should be set to 0 on x86 and all modern ARM systems (ARMv6+)
What version of the product are you using? On what operating system?
head of git repo on linux
Please provide any additional information below.
The line of the configure script is incorrect. It looks like the author
wanted the numbers to be sequentially increasing, however 2 is repeated
twice.
*buf = 1; *(buf +1) = 2; *(buf + 2) = 2; *(buf + 3) = 3; *(buf + 4) = 4;
The test for the buffer is incorrect, i should be dereferenced (*i).
return (84148994 == i) ? 0 : 1;
Thanks,
Ali
