#9930: By default, a source code would get overwritten by executable on *nix -------------------------------------+------------------------------------- Reporter: Rufflewind | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.8.4 Keywords: | Operating System: Architecture: Unknown/Multiple | Unknown/Multiple Difficulty: Unknown | Type of failure: Other Blocked By: | Test Case: Related Tickets: | Blocking: | Differential Revisions: -------------------------------------+------------------------------------- If I have a source code without an extension, say `foo`, and I forget to specify the output file via `-o`, GHC will overwrite it with the executable itself after compilation. This occurs only on *nix-like operating systems. Presumably something similar could happen on Windows – fortunately, those who use `.exe` for source code are probably among the minority. Minimum example: {{{#!sh #!/bin/sh echo >foo 'main=undefined' ghc -x hs foo less foo # 'foo' now contains binary data }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9930 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
