Segfault using call/cc on ia64 (and possibly others)

Segfault using call/cc on ia64 (and possibly others)

[Andreas Rottmann]

Hi!

As I already reported to the Debian BTS
(http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=291551), Guile 1.6.7
segfaults on ia64 at this code:

(call-with-current-continuation (lambda (k) (k #t)))

Segfaults in the G-Wrap testsuite[0] seem to indicate that this might
be a problem on alpha, hppa and sparc (segfaults there as well),
though I haven't confirmed that this is the same problem, except for
sparc, where the above works, so it looks like it could be a
64bit-specific problem.

[0] http://buildd.debian.org/build.php?pkg=g-wrap, see the logs for
    1.9.3-2

Regards, Rotty

Your one-liner seems ok for me on alpha.  Propose something for the
test suite in any case.

This means I'm going to have to investigate this G-Wrap testsuite
segfaults further on at least alpha and sparc.

A. Because it breaks the logical sequence of discussion
Q. Why is top posting bad?
