I encountered this same error and tried deleting the entire source tree
and configuring for 64bit using ./Configure aix64-cc --prefix=/usr/local.
I still got the same segmentation fault as B via RT did. So I started
trying to find out why. I modified the make file to add the -g debug
option (I'm sure there are better ways to turn on debug). That wasn't
enough to get a meaningful stack traceback I also had to add -qfullpath
-qsymtab -qtbtable -qkeepparm to get the traceback, and all the function
parameters.
Since the seg fault created a core file, I was able to look at the stack
with dbx and I found the problem -> I <- was having.

As the stack traceback shows, the BIO_write function calls the file_write
function with what is supposed to be the buffer to be written as the
second argument. What the traceback also shows is that the argument
'in = (nil)'. Reviewing the code between lines 176 (start) and the
file_write function call (line 201), we can see that nothing should
have set the in argument to nil (or NULL). But the stack traceback
doesn't lie, it is nil. With that in mind, I figured the optimizer was
causing this and removed the -O from the Makefile.
That fixed it! The entire test suite completed. But no optimization?
bummer.
So I thought of using a #pragma in bio_lib.c. To insure that no other
systems would encounter the pragma I placed a #ifdef OPENSSL_SYSNAME_AIX
around the pragma.
I tried a number of different pragma's and I haven't yet successfully
passed the
"convert a certificate into a certificate request using 'x509'" test.
I am now wondering if there is a buffer overrun or other pointer math
getting messed up somewhere else that is stomping on pointers in the BIO
struct.
I've got to get some other work done so this is going to have to wait for
me or someone else to figure out later.
For now deleting the -O (cap o) in the CFLAG of the Makefile after running
./Configure seems to work.
In closing, I should mention I did find some other errors in the make
test and I don't know enough to know if they are related. I included
them below for completeness.

ERROR in CLIENT

There are actually a good number of the last error repeated, but I
didn't want this to get any longer.
Hope all this helps
