[M3devel] segmentation fault upon ./install-cm3-compiler.sh upgrade

[Jay]

Personally I would try checking out the current tree.
And I thought there was a 5.5.x build to start from. I'd try it.
And if the existing binaries don't have symbols, and you can't build the system, find a system you can build or cross build from and get symbols in there and then debug it here.
Symbols can be very valuable and I have mixed thoughts on stripped binaries.
 
Maybe I'll get around to running this x86 Linux stuff in a virtual or physical machine sometime soon.
Hopefully this gets solved before I resort to it.
