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

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.
Regards,
Rob.
