In may original test I was relaying on LD_LIBRARY_PATH to have current folder in the values. And there was no checking of dlopen result for simplicity. Here is updated code. It will search for libloader.so in current folder. #include <dlfcn.h> #include <string> #include "loader.h" typedef void *pfLoader(std::ustring&); int main(int argc, char* argv[]) { void * libHandle = dlopen("./libloader.so", RTLD_NOW|RTLD_GLOBAL); if (0 == libHandle) { printf("Can not load \"./libloader.so\".\n"); return 1; } pfLoader* pF = (pfLoader*)dlsym(libHandle, "read_string"); if (0 == pF) { printf("Can not find function \"read_string\" in libloader.so\n"); return 2; } std::ustring s; // s.reserve(1); // uncomment this line to prevent abort pF(s); return 0; } -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31368
