Hi,

We have a problem with the Seaside tests in Squeak 5.1. The underlying issue is that source code lookup fails in headless mode on Linux (not reproducible on macOS). To reproduce evaluate in headless mode:

Object compile: 'foobar ^ [ 1+ 2] value "blah"'. (Object>>#foobar) getSourceFromFileAt: (Object>>#foobar) trailer sourcePointer.

This will signal an error (RemoteString past end of file). (Note: I checked the alternative conditions in CompiledMethod>>#getSource: the method trailer has no temp names, no #source property but has a source pointer).

I would appreciated it if someone would look into this.

I tried putting your example code into a start script (a file that is evaluated at image startup), and I get the same error. This is on an image with display open (not headless), so it may not be related to headlessness.

I am not sure what the issue is here, but it will probably be easier to debug with the display open :-)

Hi Max,

I just pushed Files-ul.172 to the Trunk, which contains a fix for this. If it turns out to be a good fix, I'll backport it to 5.1.
