Description of problem:
The following code gives a response of "Didn't find a match (for
regexec)." when it should give "Success."  Originally submitted to gcc
but they said this is a bug in glibc and to report to vendor.  Problem
does not show on glibc-2.2.5-40.

Using gcc version 3.2

#include <iostream>
#include <sys/types.h>
#include <regex.h>

const char* haystack = 
"2\n3";

const char* needle =
".+\n3";


int main()
{
  using namespace std;
  regex_t r;
  int failed_p = regcomp(&r, needle,
			       REG_EXTENDED | REG_NOSUB);
  int result = regexec(&r, haystack, 0, NULL, 0);
  switch (result)
  {
  case REG_NOERROR:
    cout<<"Success."<<endl;break;
  case REG_NOMATCH:
    cout<<"Didn't find a match (for regexec)."<<endl;break;
  case REG_BADPAT:
    cout<<" Invalid pattern."<<endl;break;
  case REG_ECOLLATE:
    cout<<" Not implemented."<<endl;break;
  case REG_ECTYPE:
    cout<<" Invalid character class name."<<endl;break;
  case REG_EESCAPE:
    cout<<" Trailing backslash."<<endl;break;
  case REG_ESUBREG:
    cout<<" Invalid back reference."<<endl;break;
  case REG_EBRACK:
    cout<<" Unmatched left bracket."<<endl;break;
  case REG_EPAREN:
    cout<<" Parenthesis imbalance."<<endl;break;
  case REG_EBRACE:
    cout<<" Unmatched \\{."<<endl;break;
  case REG_BADBR:
    cout<<" Invalid contents of \\{\\}."<<endl;break;
  case REG_ERANGE:
    cout<<" Invalid range end."<<endl;break;
  case REG_ESPACE:
    cout<<" Ran out of memory."<<endl;break;
  case REG_BADRPT:
    cout<<" No preceding re for repetition op."<<endl;break;
  case REG_EEND:
    cout<<" Premature end."<<endl;break;
  case REG_ESIZE:
    cout<<" Compiled pattern bigger than 2^16 bytes."<<endl;break;
  case REG_ERPAREN:
    cout<<" Unmatched ) or \\); not returned from regcomp."<<endl;break;
  default:
    cout<<"unknown result:"<<result<<endl;
  }
}

Version-Release number of selected component (if applicable):
