* Backport of2c7797182ato v5 branch. * Check return value of cs_vsnprintf for negative values. This prevents underflow of SStream.index. This bug was reported by Github user Finder16. * Add overflow check before adding cs_vsnprintf return value. * Backport ofcbef767ab3into v5. The overflow was reported by Github user Finder16
