I am making heavy use of latex strikeout for a report I'm preparing in org
mode. I defined a macro for the necessary latex snippet, but the argument
gets truncated on export.

MWE:
----
* Section
{{{stk(The argument for this macro is several lines long. It seems
that after a certain length, the macro argument gets truncated, as the
tex output from exporting this org buffer contains a properly
terminated strikeout block with only part of this text.)}}}
#+MACRO: stk @@latex:\sout{$1}@@

----
C-c C-e l L produces:
----
....
\sout{The argument for this macro is several lines long. It seems
that after a certain length}
% Emacs 24.3.1 (Org mode 8.2.7c)
----

I see no mention of any reason for this in the macro node of the manual or
on list archives. Am I doing something wrong or is it a bug?
