Rob,
Thank you for putting up with this. We're gradually making progress.
I've pushed a further change and this example now seems to work. I
didn't actually get that assertion fault but something similar.
Regards,
David

David,
Thanks again, but I've got two ProofPower source files further on and then I
get a different assertion failure:
Assertion failed: (val.AsAddress() > descr->originalAddress && val.AsAddress() <=
(char*)descr->originalAddress + descr->segmentSize), function RelocateAddressAt, file
savestate.cpp, line 929.
I've attached a tarball with the evidence. This time it doesn't seem to be
deterministic, sometimes it
gets further than others.
Regards,
Rob.

Thanks, both of you for your contributions. I've had another look at it and
I've applied another fix. The problem was really that it was reading beyond
the end of an array which meant that whether and how it failed depended on the
values it found. Hopefully the latest fix (e968c38) will solve it but let me
know if there are still problems.

David,
I also get a failure building ProofPower but not the same as Rob:
pp-ml: savestate.cpp:881: void LoadRelocate::AddTreeRange(SpaceBTree**, unsigned int,
uintptr_t, uintptr_t): Assertion `s >= r && s <= 256' failed.
This is on a Linux x86_64 machine and occurs with commit 524fe72 (I haven't
tested 04d3c95). Rob's second example (20171112) should reproduce this but
doesn't. I modified the example as attached to use a single session and it
gives the following error message but I don't know if this error is related:
pp-ml: gc_mark_phase.cpp:743: void CheckMarksOnCodeTask(GCTaskId*, void*, void*):
Assertion `obj->ContainsNormalLengthWord()' failed.

David,
Thanks. Unfortunately, after pulling your fix, I get the same assertion failure
2 files further
on in the ProofPower build. The attached tarball contains files similar to the
ones I sent
yesterday to exhibit the problem.
Regards,
Rob.

Thanks for doing that. I've pushed a commit that seems to have fixed it.

We are approaching the point at which the current version of Git master is
ready for release as Poly/ML 5.7.1. Version 5.7 introduced a number of
significant changes and it has taken quite a bit of work since then to fix
various bugs and sort out performance issues. I've been working with Makarius
on dealing with those that affect Isabelle and we now seem to have dealt with
everything. I'd like to ask everyone to try out the current version and let me
know if there is anything that would stand in the way of a release.
The ProofPower build fails with an assertion failure:
Assertion failed: (t->tree[r] == 0), function AddTreeRange, file savestate.cpp,
line 896.
This is on Mac OS Sierra 10.12.6 with Poly/ML version v5.7-283-g04d3c95 .
I haven't tried any other OSs. I presume this is happening where my main
program calls
PolyML.SaveState.loadState.
I've attached a tarball of a cut-down set of source files that exhibits the
problem
together with a shell script that simulates what the ProofPower make file does.

Rob.
