Sure.  

Using `tex-mode' from textmodes/tex-mode.el (rather than from
AUCTeX):

(find-file "/tmp/a.tex")
(insert "\begin")
(find-tag-default)  ; on the same line as "\begin"

Error: scan-error; Data: (Containing expression ends prematurely 2 2)

This happens because tex-mode defines a function for
`forward-sexp-function' which looks for "\end".
`find-tag-default' assumes the regular forward-sexp function which
only considers single-character syntaxes (and thus would never
error if point is after \(\sw\|\s_\)+ )
