Modified Files: src/external/historical/nawk/dist: lex.c Log Message: Do not use index out of bounds in nawk $ awk '{w=$1}' < /dev/null /public/src.git/external/historical/nawk/bin/../dist/lex.c:476:16: runtime error: index -1 out of bounds for type 'const Keyword [46]' There used to be documented a bug in the code that index ouf of bounds can in theory fault (by daniel barrett). Before assigning the pointer, first check for the index whether it's not not -1. This was a suggested solution in the comment in the code. The sanitizer is overcautious as this pointer wasn't dereferenced, but fix is nonetheless.
