<font face="Georgia">I've come to understand a bit about why the VM
was crashing when making requests via SqueakSSL. For some sites I
could make request after request with no ill effects. A successful
request/response looks like this:<br>

and this can repeat many times as request after request succeeds.<br>

Other sites would crash the vm after a small number of requests.
With the insertion of enough "String new" calls in the right
place, the crash could almost be guaranteed to occur on the first
attempt. A failure looks like this:<br>

<br>
errSSLClosedGraceful -9805 <br>
The connection closed gracefully.<br>
Available in OS X v10.2 and later.<br>
<br>
this is the only SqueakSSLWrite: not immediately following a
sqEncryptSSL, so where did it come from? I don't know, but I do
know it's using the same buffer provided in the last sqEncryptSSL
call. The problem is that this buffer was a method temp and may
well have moved or been gc'd in the interim. My hack was to make
the buffer used by encrypt and connect a permanent one to minimize
the chance of movement. Just to verify, I zeroed this buffer once
the request had been sent and checked it after the response had
been received. This is what it looked like:<br>
<br>
#[0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 21 3 1 0 22 183 80 173 250 155 255 108 25 132 220 40
109 216 134 178 73 243 155 35 75 231 89 0 0 0...<br>
<br>
the 27 bytes indicated in the squeakssl log output were inserted
in this buffer at the next output position. Not sure why this
extra write happens where it does or if it happens in other OS
configurations, so the real fix is still a mystery. I think I can
live with the global buffer for my purposes.<br>

I figured out where the "console" ends up and you are
right - is was last object overwritten. File attached
if it's of any use. My testing has proceeded to the
point that repeated calls to "SqueakSSL google:
'squeak'" work fine, but calls to a very similar
method connecting to a different host will crash the
vm after a few iterations.<br>

<div><br>
</div>
<div>At this point I would switch to gdb, set a breakpoint
in error, run the reproducible case, then use</div>
<div><br>
</div>
<div>call printOop(objectBefore(freeStart))</div>
<div><br>
</div>
<div>to find out which object was overwritten. That may be
a good enough clue to find out where the overwriting is
occurring. You can try</div>
<div><br>
</div>
<div>call longPrintOop(objectBefore(freeStart))<br>
</div>
<div><br>
</div>

</div>
<div>Yes. But there should hopefully be the
output of error on the console and that would
disambiguate between the two possible causes.
This is the stack:</div>

</div>
<div><br>
</div>
<div><br>
</div>
<div>The first means that something wrote past
the end of an object and this was detected
when a new object was allocated, seeing that
freeSpace did not contain the pattern
expected. This e.g. happens when passing
buffer objects to foreign code which writes
beyond the object.</div>
<div><br>
</div>
<div>The second usually means infinite
recursion. Looking at the memory map at the
end of the error report I think that the error
is last object overwritten.</div>
