getChar + Ctrl-C on Windows in GHCi breaks

C:\Documents and Settings\Admin>ghci
GHCi, version 6.8.1: http://www.haskell.org/ghc/  :? for help

Prelude> getChar
<interactive>: exception :: GhcException

After getChar, I pressed Ctrl+C, which prints the message about exception. After this the program becomes entirely unresponsive to any keys, including Ctrl+C.

I ran into this bug attempting to create a minimal test case for a bug where pressing Ctrl+C while at a getChar results in:

*: internal error: stg_ap_pv_ret
    (GHC version 6.8.1 for i386_unknown_mingw32)
    Please report this as a GHC bug:  http://www.haskell.org/ghc/reportabug

Unfortunately I have no minimal test case for the latter bug, it is unreliable to duplicate, and the dependency list is sufficiently massive that it takes me a couple of hours to get everything installed and ready. They are possibly related.

WindowsXP, standard Windows shell, GHC 6.8.1.
