[racket] weird build failed after changing one character in docs that shouldn't affect anything

Before noticing this email, I noticed that the build had failed on
Racket HEAD with a segfault. Builds for all other Racket versions were
OK.

I figured it was some temporary weirdness on HEAD, and without
thinking much, I restarted the build on Travis.

This time it succeeded fine, even on HEAD.


If I'd noticed this email first, I would have copied the exact
segfault message. Unfortunately now I can't find it on Travis.
Although Travis keeps a build history, that doesn't seem to include
errored builds that you manually restart.
