There is no possibility that nsize is larger than the usable buffer size after extend_alloca. - If one does not want to use the extending feature of extend_alloca then one should just use alloca. -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
