Boost regex Segmentation fault on Linux

zijian · 02-21-2009, 10:54 PM

Hi,I am trying to use the famous Boost regex library and write a c++ code like this:
1 #include <boost/regex.hpp>
2 #include <iostream>
3
4 using namespace std;
5
6
7 int main(void)
8 {
9 boost::regex reg("test");
10
11 bool b = boost::regex_match("A test string", reg);
12
13 if (b) {
14 cout<<"Success"<<endl;
15 }
16 else {
17 cout<<"Failed!\n";
18 }
19
20 return 0;
21 }
It's compiled and linked quite well, and when run it, got the segmentation fault. After I debug it, I found it was core dump at line 11
.
Segmentation fault.
0x08048f68 in ~repeater_count (this=0xbfc5c378) at /usr/include/boost/regex/v4/perl_matcher.hpp:270
270 *stack = next;

But it works very well in Visual studio 2005.
Anyone could give some help?

It works on my machine, Slackware 12.2 with the boost package from testing/, gcc 4.2.4

What exact platform are you using?

Also, in the future, use [code] tags when posting, like

Code:

#include <boost/regex.hpp>
#include <iostream>

int main(int argc, char **argv)
{
   boost::regex reg("test");

   bool b = boost::regex_match("A test string", reg);

   if (b) {
      std::cout << "Success" << std::endl;
   }
   else {
      std::cout << "Failed!" << std::endl;
   }

   return 0;
}
