------- Comment #2 from hxdg21 at yahoo dot com 2009-09-30 03:09 ------- Thank you for the clarification. My friend and I ran across this while comparing the assembly generated by different compilers/platforms when manipulating strings. A largely academic exercise. That piece of code did not look right to me at first but what threw us off is the fact that the code worked with the Sun compiler and that -Wall -pedantic on gcc did not give us any warnings. We were puzzled by it.
You are correct though. I checked the standard and it does specify that the result of such operation is undefined, which explains why it may work with some compilers but certainly something that shouldn't be relied on. Thanks again -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41318
