Technically, this is a latex fragment, not a latex environment (which is
what I suggested to use). The difference is that the former is inline
(i.e. it is contained in a paragraph) whereas the latter isn't.
Non-inline elements always have precedence over inline ones.

I see. This should be fixed. Thanks for insisting.

A package is conflicting with "amsmath", probably "wasysym". Try to add
"nointegrals" option to "wasysym" in `org-latex-default-packages-alist'.
