Matthew,
Before upgrading to the version when you fixed this
(or possibly other) crash, I have tried for a long time
to catch it under gdb or rr (Sam, thanks for the pointer to rr).
Unfortunately, the program has never crashed under gdb or rr.
I do not know why. I ran it many times, and it works

Hmm, I gave it a shot, and this seems to work. Not sure if it'd be especially
useful. But fwiw

You rec
[[:space:]] and similar matchers also require #px.
As for the difference between #rx and #px:
"The pregexp ... procedures produce a regexp value using a slightly different
syntax of regular expressions that is more compatible with Perl."
That must be the only thing in Racket influenced by Perl.

To use \s as a matcher, you need #px not #rx:
(define rx-empty-or-all-blank-string
;#rx"^[[:space:]]*$")
#px"^\\s*$")

hi,
I must be overlooking something basic, but can't figure out why the second and
third tests here fail. (Makes no difference whether I spell {space-character}
the [[:space:]] or the \\s way.)
I'd be grateful for enlightenment. :)
Cheers,
Tim

I just pushed a fix for these issues. Thank you!

This question has been asked in 2012 and the fact that no reply has been posted
makes me think this is a dead track. But nevertheless...
I see that during a debugging session I can hover above an expression and
rightclick to send its value to the console or so set! it something else.
