Hello,
When ~code~ is converted to LaTeX, it becomes \verb~code~; i.e., it uses
a potentially "dangerous" character, in this case `~' which is active.
In most cases, it is unnoticeable, but in some environments, it breaks.
The solution is to protect the command, what the attached patch does.
PS- Nicolas, can you apply this one without problem?
Best regards,
Seb

I'm not sure it solves the problem. I had looked at this problem five
years ago and had concluded that \protect was a bust, because \verb is
special - see
http://thread.gmane.org/gmane.emacs.orgmode/14256/focus=14257
Maybe I got it wrong back then, but I thought I'd bring it to your
attention.

If this is the problem, would a simpler solution be to remove ~ (and other
special characters, like #^_$) from ‘org-latex--find-verb-separator’?
But as Nick points out, the problem with \verb is probably deeper. The
protectedtexttt case in ox-latex already implements the suggestion from
the thread he linked. Perhaps the solution is to change the code entry
in ‘org-latex-text-markup-alist’ to use protectedtexttt and drop the
verb case entirely from ‘org-latex--text-markup’. What do you think?
Thanks,
