A quick search reveals that we're not the only ones suffering from this:
https://issues.apache.org/bugzilla/show_bug.cgi?id=55696
http://lists.gnu.org/archive/html/bug-bash/2013-07/msg00011.html

There's a reference around to the code in question:
http://www.opensource.apple.com/source/Libc/Libc-997.1.1/secure/strcpy_chk.c
And it seems to be enabled by:

#if defined (__GNUC__) && _FORTIFY_SOURCE > 0 && !defined (__cplusplus)
/* Security checking functions. */
#include <secure/_string.h>
#endif
in
http://www.opensource.apple.com/source/Libc/Libc-997.1.1/include/string.h

So, if I understand it correctly, this only happens if _FORTIFY_SOURCE
is enabled. Not sure what does that on Matthias but not your machine.

Greetings,
