Daniel,
i did a repull from git, compiled, installed and re-test of Kamailio and
got the same error in the same program's location as previous (in
tm_funcs.c). Here are the commands that I entered to make sure I did
everything correctly:
mkdir -p /usr/local/src/kamailio/kamailio-3.2-noalignment
cd /usr/local/src/kamailio/kamailio-3.2-noalignment
git clone --depth 1 git://git.sip-router.org/sip-router kamailio
cd kamailio

Hello,
thanks for troubleshooting further -- as I expected, it is a memalign
problem, but some confusing reports by not using always the patches I
made to registrar module to align the structure, made thinking is
something else. Now is no longer in registrar, but in another module.
There might be many of these, can you try to compile first without
strict alignment to 8 bytes? Checking quickly to gcc, the option
should be |-mno-faster-structs
So try:
make proper
make FLAVOUR=kamailio cfg|
make Q=0 CC_EXTRA_OPTS=|-mno-faster-structs all|
...
By providing Q=0, you will see all compile flags, verify that
|-mno-faster-structs is there.
Cheers,
Daniel

Hello,
After doing some research, this is what I found out. On Solaris Sparc
64bit system, there is a mandatory alignment of memory accesses and
also for data types. I went thru the core dump, disassembled the code
and located the instruction that produced the error. The registers
addresses in questioned are on a 4 byte alignment but not an 8 byte
or 16 byte alignment. .The earlier patch must have forced the
alignment which is why the error did not occur in the program
common.c. It looks like there is a similar situation in t_funcs.c.
Here is a link that I found that can better explain:

I hope this helps in trying to resolve this problem and to find a
solution. Also, if you need a sparc system to test with, just let me
know. We can help from a sparc perspective.
Thanks
Nathaniel
