Hi Eliot. We are doing a crazy experiment where we serialize almost all PharoCore and we materialize it in a PharoKernel image. During the initialization (after the load), there is one line that crashes Cog:

PolymorphSystemSettings showDesktopLogo: true.

For what I can see, I may be related to the fact that #pharoLogoContents is too long or something like that?

the same experiment with StackVM works fine.
Of course in a normal image (without this experiment) I can do PolymorphSystemSettings showDesktopLogo: true. without problems.


From gdb i see:

And the line that fails is:     allocateOpcodesbytecodes((numBytecodes + extra) * 10, numBytecodes);

numBytecodes is 49729 and extra is 10.

Any idea?

thanks!
