boost regex seg fault, can't run a single example....
Greetings
I've just emerged (I'm using gentoo) boost, once using bjam and another time
without it. In both cases (not that it could make a difference) I just can't
get the boost_regex to work. It blows...
After compiling a few examples (captures_example, and grep) in both my home and
work pc. I get the same result... segmentation fault.
While running captures_example in the line
std::cout << " $" << i << " = \"" << what[i] << "\"\n";
After doing some debug, I was able to find only the consequence. (I didn't
search that hard...)
In sub_match.hpp:73
result.append(1, *i);
the value of i is 0x1<address out of bounds>.
the line match_results.hpp:123 supposly returns
const boost::sub_match<__gnu_cxx::__normal_iterator

The program captures_example is special: to build it you must define BOOST_REGEX_MATCH_EXTRA *both* when building that example, and when building the regex lib's. This does not apply to any other examples though. The error's you're seeing have all the hallmarks of some kind of binary incompatibity issue. I suggest you build the test programs with bjam: cd into libs/regex/test and bjam regex_regress If that passes OK then it's likely that the installed lib's on your Gentoo system are the problem. John.
Thanks
That's almost for sure the problem. I did link the program but with the wrong
libs. But the other examples work ok, and they do everything that one might
expect (a perl replacement). So I just end up letting it go.
Thank you.
