I am compiling 3.6.11 from amalgamated sources on Solaris and I get a
Segmentation Fault whenever I type something at the shell. Pasted
below are some information which might be helpful. Does anyone else
see this error or have a workaround?
I get the same behavior when I run in gdb or just from the command
line. In both cases, as soon as I type anything at the shell, such as
".tables" or a create table command, it immediately crashes. I am
compiling statically and installing into my homedir, which I don't
imagine should cause any problems. If I compile shared, I get the same
error.
It looks like previous bugs (700, 1158 in particular) saw
memory-alignment-based crashes. In the traceback, you can see that
there is an assignment to a memory location like 0x10591c. This
indicates that it is not 16-byte aligned. If I add __attribute__
((__aligned__(16))) to the definition of prereqRight, I see a
different alignment, but still not correct (something like 0x10588c).
