GHCI core dumps when used with VTY
Load the attached script in ghci:
$ghci ghci-coredumper.hs
(you need the vty-menu package from hackage) and type die
>die
You may see a menu with a set of ten numbers. If you do press enter repeatedly. Eventually it will core dump(at least it does for me) Unfortunately I have been unable to collect this core dump, but here is the output at least:

Neúspěšně ukončen (SIGABRT) (core dumped [obraz paměti uložen])
Sometimes it dumps immediately, sometimes it takes a while.
Sometimes the errors are different:
*** Exception: user error (Terminal does not define required capability "cup")
*Main>
*** Exception: user error (Terminal does not define required capability "setab")
*Main>
<stdin>: hWaitForInput: end of file
But mostly it just core dumps.
