It would be better if runtime_error() included printf-like capabilites,

How does reserving 12 bytes on stack can help to prevent a segfault?
I can imagine how aligning the stack can help, but here gcc 4.2.1 does
something diffrent.
Maybe just throw an URL to more
--- Comment #5 from rask at sygehus dot dk 2007-07-22 22:56 ---
The point is exactly to align the stack. The call instruction decrements %esp
by 4 bytes, so GCC has to decrement %esp by another 12 bytes to keep the stack
aligned. See also bug target/13685.
