bug#11083: guile-2.0.5 bug report

[Mark H Weaver]

Hi Kiyoshi,

Kiyoshi: would you be willing to help investigate further?  I would
recommend running the 64-bit version of Guile in a debugger, setting a
breakpoint on 'environ_locale_charset' and stepping through that
function to find out more precisely where the bad pointer originates.

    Regards,
      Mark
