I suspect misaligned_stack_error_ appears only in some kind of debug mode.
Could you disassemble the library with otool and check whether do_searchovector
calls this method? It should be somewhere at the beginning of the function.

http://developer.apple.com/library/mac/#documentation/Darwin/Reference/ManPages/man1/otool.1.html

This says:

-t     Display the contents of the (__TEXT,__text) section.  With the -v flag,
this disassembles  the text.  And with -V, it also symbolically disassembles
the operands.


Search for do_searchovector and misaligned_stack_error_ should be called in the
first 20-30 lines of the function body.
