Some ideas:
- Do you use Weak* anywhere? This includes SeasidePlatformSupport
class >> #weakDictionaryOfSize:
- Dou you use OSProcess?
- Can you use gdb and attach to the image and print the callstack?
for redirecting stdout and stderr

Not after two seconds. But else yes. That's just some of the things
you have to accept when using Squeak.  Why? Because Squeak is a toy
and this is good because we are all still kids.
I can tell you more horror stories if you buy me a beer.

Can't you just download and compile it?

If it works fine on Windows and blocks on Linux .....
