The crash stack points to this code http://hg.python.org/cpython/file/302c8fdb17e3/Parser/myreadline.c PyOS_Readline() function calls readline code. There is another piece of code related to readline in Python http://hg.python.org/cpython/file/302c8fdb17e3/Modules/readline.c I'll try to debug it with '-g' later today and hopefully find more useful information. _______________________________________________ Bug-readline mailing list [email protected] https://lists.gnu.org/mailman/listinfo/bug-readline
