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></font></div></blockquote><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>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>There are two possible errors

<div>error("last object overwritten");<br>
</div>
<div>error("out of memory");<br>
</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>
