error in process filter: Stack overflow in regexp matcher

[nenad mitrovic]

I am trying to execute this piece of code: (rest (file-seq (file (str "corpus/" "ham"))).

When I execute I get this error: "error in process filter: Stack overflow in regexp matcher".

I have 1400 files in corpus/ham folder. But when I execute only three file it works.

I have just tried to reproduce a similar case on a system running Mac OS X 10.13.6, Oracle/Apple Java 1.8.0_192, Clojure 1.9.0, and Leiningen 2.8.3, and a directory containing 1400 files.  I did not see the error you did.

What versions of OS, Java, Clojure, and anything on top of Clojure (e.g. Leiningen) are you using?

If you are using Leiningen, what is the contents of your ~/.lein/profiles.clj and project.clj files, if any?  Some add-on plugins that modify what is shown in the REPL, e.g. that auto-pretty-print results, can have errors parsing some input, or printing some output, even if Clojure by itself has no problems.  If you can reproduce your problem using a `clj` command line that avoids using Leiningen, for example, that would help determine whether it is caused by something in your Leiningen setup, vs. elsewhere.

I would recommend trying to temporarily rename ~/.lein/profiles.clj to a different name, so that there is no such file with that name any more, and try your file-seq expression again to see if it behaves any differently.

This isn't a clojure issue.

A reference to "process filter" indicates this is an emacs problem. Its regex syntax matcher tends to blow up on long lines.

Thank you Andy, after I changed ~/.lein/profiles.clj file to a different nam, it works now. I can see all of 1400 files.
