Can anyone explain the difference between these versions of Ubuntu?
I installed 11.10 i386 and wrote some C code that worked fine in that platform but failed to work in 11.10 amd64 on the same machine.
After debugging with valgrind and gdb I got that I was getting segmentation fault in a call to realloc() with an argument mem_ptr and size 0 passed to it.
I learned here that i386 is also referred to as 32-bit and amd64 as 64-bit, but what does this mean?
CPU: Intel i7 2nd generation
