Probably it is nothing, but valgrind shows some strange behaviour in
xerces initialization. The code is very simple:
int main(){
XMLPlatformUtils::Initialize();
XMLPlatformUtils::Terminate();
return 0;
}
The valgrind reports some errors (see attachment) that look more like
problems in linux libc libraries, but I'm not sure. Can someone explain
this behaviour? I'm using the latest xerces 3.0, compiled from the
source code and I am on ubuntu 8.04. Thanks.
