#11346: GHCi can crash when tabbing a filename ------------------------------+------------------------------- Reporter: honnza | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: GHCi | Version: 7.6.3 Keywords: | Operating System: Windows Architecture: x86 | Type of failure: GHCi crash Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: ------------------------------+------------------------------- The following sequence of actions: 1. Type `:: I` into GHCI 2. Press the tab key 3. Hold backspace to erase the resulting text 4. Repeat steps 2 and 3 May result in the following appearing in the console: {{{ Prelude Data.Map> :: ImageExpo.config ghc.exe: panic! (the 'impossible' happened) (GHC version 7.6.3 for i386-unknown-mingw32): Prelude.chr: bad argument: (-947713851) Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug }}} followed by the system prompt. Afterwards I have realised that `::` was actually interpreted as a GHCi command rather than the type designation syntax. Tabbing yields all files in the current directory, but actually performing the command yields `unknown command '::'` There is only one file that starts with `I` in my current directory.
