[Jsoncpp-devel] g++ version problem??

[Joakim H. <jo...@st...>]

Hello,

I have downloaded jsoncpp and successfully built it; I also issued the command "scons platform=linux-gcc check" to run the tests - the all passed.

I then created my own program to actually test this; the program compiles and links fine - but it goes down witn SIGSEGV when running. My program is

#include <json/json.h>

void parseJson() {
    Json::Reader reader;
}

int main(int argc , char ** argv) {
    parseJson();
    exit(0);
}

I.e. it is very simple stuff. When I try putting the Json::Reader instance in the boyd of main{...} it seems to work.  A backtrace from gdb is inlined below:

#0  0x0000003a560b7672 in __gnu_cxx::__exchange_and_add () from /usr/lib64/libstdc++.so.6

As you can see I have a very old version of g++ (4.1.2). I am in a corporate environment and it is quite painful to get a newer version - do you think this can be the problem?
