This fixes the
c/weaver/chl-collitem-subst.wvr.c
problem in goblint/analyzer#1356.Because the logic of making locations synthetic is "Change all stmt and instr locs to synthetic, except the first one." and the
first
flag indicates whether the current statement is first, the logic should be flipped. That is, the first location should not be made synthetic.It's surprising that this complete logic flip didn't reveal itself from the very beginning of synthetic locations. This could be the reason we couldn't verify so many of our own witnesses even.
