- removed unecessary changes ahead of VMMaker.oscog-eem.333 version (those stamped LucFabresse)<br></div>- carefully applied changes from VMMaker.oscog-eem.333 that were not applied<br></div> Note that this version was marked as merged, which it was obviously not<br>
</div> Please, if you do not fully merge, but just cherry pick some changes, it's better to not merge.<br></div>- upgraded to (merged) VMMaker.oscog-eem.335 because it fixes a snafu<br></div><div>- integrated the issues for which I emitted a pull request<br>

<div><br>I cannot tell which missing change exactly was the root cause,
and I cannot dissect either, but I saw several + LiteralStart missing...
Or it could be related to cogit method/block native code generation...<br>The changes are most probably here<br><a href="https://github.com/nicolas-cellier-aka-nice/pharo-vm/commit/af718618eee516d15c0b362123e3a77c8b6fd2e8">https://github.com/nicolas-cellier-aka-nice/pharo-vm/commit/af718618eee516d15c0b362123e3a77c8b6fd2e8</a><br>
<br></div>Bad news,<br></div>the structures at beginning of src/cm/cogit.c are generated out of order, and I didn't find the cause yet.<br></div>Once solved, I think my branch should be carefully reviewed and integrated.<br>

</div>Uhm, why? They haven’t changed.<br></blockquote><div><br></div></div><div>Sorry, haven't changed means that there's no diff with the corrected version.<br>IOW, the fixes from Eliot have been integrated for a long time already.<br>

Pharo vms 105 and later no longer crash, but all reliably show the bug.<br>
And 236 is the last Squeak one to show the problem.<br>
<br>
I might take a look at Esteban’s versions from the same time,<br>
228 and 229<br>
