Description E. C. Masloch 2017-09-10 13:12:51 PDT

Using a negative value for times now results in a panic, as follows:

$ nasm -v
NASM version 2.14rc0-20170624 compiled on Jun 24 2017
$ cat nasmbug.asm 
times -1 db 0
$ nasm nasmbug.asm -o nasmbug.bin
nasmbug.asm:1: panic: assertion output_ins.times >= 0 failed at asm/nasm.c:1342
$ 

Previously this would cause an "error: TIMES value -1 is negative".
