In texinfo.tex Revision 1.306 (the latest from CVS) there's a problem
where tex goes into an infinite loop with a right quote character (')
inside math-mode @tex regions.
Sample file is attached, with log file (the error location is shown
from hitting C-c in the infinite loop).
The problem does not occur with texinfo-4.13. Sorry I'm not a
sufficient Texpert to suggest any solution.
\input texinfo
@tex
$$
F_L'(\eta,x) = fcp[k_L] * \exp(exp_F)
$$
@end tex
@bye
