[CWB] "Segmentation fault (core dumped)" on various versions

[Stefan Evert]

Dear Scott,

glad to hear that this appears to have helped.

I've had similar problems myself recently.  One possibility is that recent development efforts introduced a bug in the indexing code that has been fixed again; so if you happened to build the index with one of the broken versions, it ended up damaged.  Difficult to track this down, since the current version (as well as release 3.0.1) appear to work fine.

Do you happen to have copies of the old and new .crc and .crx files? Comparing these might give us a hint where the problem lies, though I don't think I'll have time for an in-depth look anytime soon.

Best wishes from Lancaster, where I am attending a conference co-organized by Andrew,
Stefan
