|reopen| bugnumber

The proposed solution, which has to bind syntax-propertize-function to 
nil before calling scan-sexp, reads like a work around. These things 
shouldn't be necessary.

Assume a fix must affect usage of syntax-propertize-function and probably is not a trivial one.
Its design seems worth further discussion.

For example reading:

"The specified function may call ‘syntax-ppss’ on any position
before END, but it should not call ‘syntax-ppss-flush-cache’,
which means that it should not call ‘syntax-ppss’ on some
position and later modify the buffer on some earlier position."

Emacs can do better.
