Re: Emacs crashes accidentally

[Richard Stallman]

    "SDATA (string)" shall be 0x243d8ac, but value of the first argument
    (PTR) of STROUT is 0x2469648.  This is the reason why Emacs
    crashed.

    But, why this happened?  Memory leak?

I don't see how a memory leak could possibly have such an effect.

Please examine the value of printcharfun and figure out what Lisp
object it is.  That way we can tell what path the code took through
strout.  And what is the value of `i' in strout's frame?

strout increments PTR as it runs.  Maybe it has incremented PTR too
far.

Or maybe message_dolog somehow clobbered the stack and altered PTR.

Basically I am as puzzled as you are.
We need more facts.
