Agreed. Thanks for the patch -- applied to CVS HEAD.

There is no portable way to build a va_list in memory to pass to vsprintf --
building an array of void* works with some compilers, provided the memory
alignment expected on the call stack matches the alignment of the array on
the heap. Worse, some compilers implement va_list's without using void*
arrays at all.
Cheers,
