Well it's a somewhat longer story. I have some code to interface via the
serial lines. And I want to do that on Windows and Linux. So far so
good. Now my code for interfacing to the serial lines works fine on
Windows. But it fails on Linux here's the debug.log from Pharo:

Where do I start or how do I start to solve this error?
You'll need to use gdb to look at the internals of the plugin code. �You might also want to build a debug VM to make the debugging easier. �Here are two places to start:
There's also Mariano Peck's blog on the VM.
