closure-common fails to load correctly after compilation

[Mark Evenson]

When compiling the fasl for closure-common/ystream.abcl an
error in StandardClass?.getClassLayout(StandardClass:205) in reading back the parameters.

Interestingly, if the system is restarted, the fasl *can* be loaded without complaint, so there seems to be some artifact of the compilation process "hanging around" in memory which causes this problem.

Unknown whether this affects the actual us of closure-common

This error existed in abcl-1.0.1 as well, so it has nothing to do with the recent work on the MOP.

Can't reproduce on current trunk.

Hope mevenson can, otherwise we should close as fixed.

[ehuelsmann]

Assigning to mevenson so it's clear that I'm waiting for his input on the reproduction.

[ehuelsmann]

Works for both mevenson and me.

CXML loads but XPath *still* borks the compiler on a hairy fasl that we need to graph to debug.
