Thanks Igor and Mariano. I recovered the image. Just in case anyone ever has
a similar problem, the solution was:
1. Test for selector in CoInterpreter>>commonSend
...
(messageSelector = #halt) ifFalse: [ "the conditional was added"
self internalFindNewMethod.
self internalExecuteNewMethod ].
self fetchNextBytecode.
2. Manually edit the condition in gcc3x-cointerp.c:
char* realSelector = GIV(messageSelector) + BaseHeaderSize;
if (strncmp(realSelector, "halt", 4) == 0)
puts("Skipping halt...");
else { ...
Although I lost the better part of a day, it's a very powerful feeling to
start building basic VM skills and know that errors that used to be magical
and fatal can now be resolved...
Cheers,
Sean
