evaluation corrupts buffer?

[acthp]

I have no idea what's happening, actually, but when doing cp% to evaluate a form, if an error is thrown during evaluation the entire contents of the buffer are replaced with a stack trace. The status line changes to this:

datasets.clj :setloclist()

where datasets.clj is the file name. I don't know why setloclist is there, or what it means.

If I open the buffer in another window with :e datasets.clj I get the stack trace. In the original window, doing u to undo the changes throws error Cannot make changes, 'modifiable' is off. If I explicitly set modifiable, u then errors out with line numbers wrong.

Is there some way to recover the buffer? The only thing I know to do is delete the buffer with :bdelete! and load the last saved version from disk.

Can you consistently reproduce this in a fresh Vim instance? Sounds like you might be accidentally editing your file from inside a location list window.

[acthp]

So far unable to repro consistently. It's happened a few times with :Eval as well. I'll try to narrow it.

[acthp]

Can reproduce it now. Steps:

:Eval (blah)
:Eval (blah)

Note that when doing the second Eval the cursor is in the original source buffer. You can move around in it, make edits, whatever. The location list window is open, but is not the current buffer. :ls shows the source buffer as the current buffer, with %.

The second step can also be cp%, and probably any other command that will evaluate an expression that may throw an error.

Where is the step where you open the location list window?

[acthp]

It opens automatically on step one (assuming blah isn't defined, and will throw an error).

Basically, it's invoked by doing an evaluation while the location list window is open, but is not the current buffer. In that scenario, the current buffer gets hammered.

If that's the case you're at least a year out of date. Update fireplace and report back if it's still an issue.

ack! Sorry, forgot I was on an old server. All better now. Thanks!
