/*

|
* The whole regression test I am after here is to call qa/kern/args with
|
||
|
|
* arguments of various lengths, in order to trigger different stack alignments
|
||
|
|
* due to varying amounts of stuff in args.
|
||
|
|
*
|
||
|
|
* It turned out that gcc compiles fprintf into something that uses
|
||
|
|
* fpu instructions which require the stack to be 16-aligned, so in
|
||
|
|
* fact the fprint for sum here would suicide the process if the stack
|
||
|
|
* it got happened to be not 16-aligned.
