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 <cstdio>
#include <cstdlib>
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.
# g++ -v
