[isabelle-dev] PolyML crashes

[Ondřej Kunčar]

Hi!
In the past couple of months I've gotten a crash of PolyML always with 
the same error message. I cannot reproduce the problem reliably but 
because it has already happened, let say, six times in the past three 
months, I am reporting the problem here:

Unofficial version of Isabelle/HOL (unidentified repository version)
poly: gc_mark_phase.cpp:432: virtual void 
MTGCProcessMarkPointers::ScanAddressesInObject(PolyObject*, 
POLYUNSIGNED): Assertion `baseAddr > (PolyWord*)obj && baseAddr < 
((PolyWord*)obj)+length' failed.


This refers to any changeset in the past three months.

Best,
Ondrej
