Yea, it is very very simple to have a library with hand coded
assembly as part of it that is missing the obscure assembly
directives that set the flags marking the text as really being
execute only and the data as really being non-executable.

Usually comparing the assembly with the assembly output from
gcc for a small function will enable you to discover the
wondrous gibberish the hand coded assembly needs to add :-).
