Well, since others definitely don't see this, including me, and I can do things like 62MB exec arrays: [torvalds@woody linux]$ echo $(find /home/torvalds/) | wc 1 883304 63000962 without getting any overflows (much less just on the kernel sources, which is less than a megabyte of pathnames), I think it would be good if you were to just instrument the kernel and make it do a "printk()" when it returns E2BIG in fs/execve.c (or the NULL returns from get_arg_page()). Just to figure out *which* test fails for you but apparently nobody else.
