Re: [babel] Multiple results blocks for the same source code

[Eric Schulte <schulte.eric@gmail.com>]

Hi Seb,

I could not reproduce the error you describe, and your test case passes
for me.  I have added your test case to testing/test-ob.el however so it
should protect from this error in the future.

You could try running the test suite in batch mode (which will not load
your configuration) and see if the test still fails for you.  If not
then the problem is probably due to either something in your config.

Thanks for the test case! -- Eric

ps. the only comments I have on the test itself are
    1. The initial placement of the point is described in the
       documentation string for the `org-test-with-temp-text' function
    2. In the future if you could share new test cases as patches to the
       relevant test file (i.e., using git format-patch) that would be
       ideal
