[vwnc] VisualWorks 7.7 - aborts with memory fault after RuntimPackager was executed

My image aborts after I have used the RuntimePackager as I am used to from VW7.6.
Does anybody know about ? Karl __________________________________________________________

It's difficult to diagnose such problems without lots of
information. Normally, if there is an error in a runtime image you will
get an error.log file written out which will give you an indication of
what the problem is. It's possible that if the system is running out of
memory you'd get a VM error and it would never get to write that. What I
would suggest for that is to run the runtime with the -xq flag, which
should do a stack dump from the VM level when it exits. That might need
to be the debug VM, I'm not sure. You can also run with the -o10s flag on
the debug VM which will write to stdout a gigantic file of all message
sends, but it's a lot of work to go through.
What I see if I package a trivial runtime with the file browser on Windows is a walkback that appears to be because it has a class shared variable DefaultEncodings which is not initialized in the runtime. I also see quite a few methods that show up in the test phase as dynamically referenced, suggesting the file browser is doing lots of clever things. I'm not sure what's going on with the shared variable, but what I'd do if I wanted to package the file browser is just put some sort of lazy initialization around access to it. My guess is that the runtime packager is actually running the variable initializer, which is nil - it expects to be initialized in a class initialize method. I would expect this is the same underlying issue you're seeing, though it's not obvious why it would show up as an out of memory on your systems. I'm in a hotel room right now, and don't have access to anything but Windows.

For testing I didn't load any of my packages/parcels, but just took the standard visual.im. I define FileBrowser as startup class and open as startup method. The test during the packaging works fine. But after all steps are through (all with default), I am getting a memory fault when I start the stripped image. I am trying on Linux system, but have the same effect on HPUX 11.
