It seems that either there is a new bug in the foreign function calling
sequence or something has changed.
I'm using the version of MLton in Debian testing:
MLton 20100608 (built Tue Jun 15 01:10:03 UTC 2010 on barber)
on a Linux AMD64 architecture.
The following program segfaults when run:
val printf = _import "printf": string * int -> unit;
val () = printf ("You are a dog %d0000", 99)
val () = printf ("Hello silly %d0000", 123)
It prints out the first line but then segfaults on the second call to
I looked in
page and what I'm doing looks like it is following the description
On Linux i386, this code works both using the Debian stable version of
MLton 20070826 (built Mon Sep 03 18:05:04 2007 on eponym)
and also a version I just built from the repository:
MLton rexported (built Tue Feb 1 23:22:44 CST 2011 on jupiter)
I thought perhaps it was something involving int vs. Int64.int, but
changing the printf type in the ML code to Int64.int made no difference
on the AMD64 machine.
