Fix some bugs in fns.c, discovered in passing while doing other work. 2010-11-14 Aidan Kehoe <kehoea@parhasard.net> * fns.c (Fnreverse): Check that non-list sequences are writable from Lisp before modifying them. (There's an argument that we should do this for list sequences too, but for the moment other code (e.g. #'setcar) doesn't.) (mapcarX): Initialise lisp_vals_staging, lisp_vals_type explicitly, for the sake of compile warnings. Check if lisp_vals_staging is non-NULL when deciding whether to replace a string's range. (Fsome): Cross-reference to #'find-if in the doc string for this function. (Freduce): GCPRO accum in this function, when a key argument is specicified it can be silently garbage-collected. When deciding whether to iterate across a string, check whether the cursor exceeds the byte len; while iterating, increment an integer counter. Don't ABORT() if check_sequence_range() returns when handed a suspicious sequence; it is legal to supply the length of SEQUENCE as the :end keyword value, and this will provoke our suspicions, legitimately enough. (Problems with this function revealed by Paul Dietz' ANSI test suite, thank you Paul Dietz.) (Freplace): Check list sequence lengths using the arguments, not the conses we're currently looking at, thank you Paul Dietz.
