[Bug c++/54591] New: sscanf format no more working

 Bug #: 54591
   Summary: sscanf format no more working
Classification: Unclassified
   Product: gcc
   Version: 4.7.1
Status: UNCONFIRMED
  Severity: critical
  Priority: P3
 Component: c++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: temp78...@mutluit.com


sscanf no more working, it was ok in prev. versions:

#include 
#include 
int main()
  {
const char*psz = " PROTO=TCP SPT=6004 DPT=26532 ";

char   szProto[256] = "";
unsigned short usSrcPort = 0, usDstPort = 0;
const int c = sscanf(psz, " PROTO=%255[^ \t\n]s SPT=%hu DPT=%hu", szProto,
&usSrcPort, &usDstPort);
printf("%s\n", c == 3 ? "OK" : "ERROR");
//...

return 0;
  }


It fills only the first field --> c=1 --> ERROR
This code was working fine in prev. compiler versions.
