Raymond Toy pushed to branch master at cmucl / cmucl Commits: b8841170 by Raymond Toy at 2018-01-27T13:04:52-08:00 Fix #49: CLM crashes When invoking motifd, the program name is #p:'library:motifd". This is passed directly to spawn (a C routine), which only accepts strings. So, before calling spawn, convert the program path to a unix namestring. This allows the example from the bug to run without crashing. - - - - - 87c07e5d by Raymond Toy at 2018-01-27T18:19:56-08:00 Make sure spawn is called with a string The previous commit worked for search lists, but the program could be a string. Take care to convert pathnames to strings so that spawn is always called with a string. - - - - - 99eb4311 by Raymond Toy at 2018-01-28T02:54:17+00:00 Merge branch 'rtoy-fix-49-clm-crash' into 'master' Fix #49: CLM crashes Closes #49 See merge request cmucl/cmucl!32 - - - - - 1 changed file: - src/code/run-program.lisp Changes: ===================================== src/code/run-program.lisp ===================================== --- a/src/code/run-program.lisp +++ b/src/code/run-program.lisp @@ -522,8 +522,18 @@ ;; Make sure all the args are okay.
