[Boost-users] [regex] Segmentation fault on regex_search only on CentOS

Subject: [Boost-users] [regex] Segmentation fault on regex_search only on CentOS

I have compiled the same C++ source on two machines:

1 - Ubuntu 11.04, 2.6.38-10-generic #46-Ubuntu SMP Tue Jun 28 15:07:17 
UTC 2011 x86_64 x86_64 x86_64 GNU/Linux
2 - CentOS release 5.3, 2.6.18-128.1.14.el5 #1 SMP Wed Jun 17 06:40:54 
EDT 2009 i686 i686 i386 GNU/Linux

On Ubuntu I have g++-4.5.2, on CentOs g++-4.4.4 and on both I have 
boost-1.42.0.

My source compiles perfectly on both machines, but on the CentOS one I 
get a Segmentetion Fault during the execution.

Using some prints, I found out where it happens:
...
boost::regex grepGPP("Monthly Ecosystem GPP", boost::regex::egrep);
cerr << "DEBUG BEFORE!" << endl;
boost::regex_search (currGPP, grepGPP)
cerr << "DEBUG AFTER!" << endl;
...

The segmentation fault comes during the execution of regex_search, 
beacause "DEBUG AFTER" is not printed.

Any ideas on how to solve this problem?

Thanks in advance.
