Subject: Convert the value before taking the shortcut in adjust_for_pointer_arithmetic(),... 
X-Git-Url: http://nsz.repo.hu/git/?a=commitdiff_plain;h=9fd4a32dd13491d99fa4998fd3a0c471eb9c41cf;p=cparser

Convert the value before taking the shortcut in adjust_for_pointer_arithmetic(), so doing pointer arithmetic with char* and a long long offset works.
