All,
I have an application which is statically linked.
It uses dlopen() and dlclose() calls multiple times.
First time the dlopen()/dlclose() pair succeeds.
But the second one fails with segfault.
This happens only in RH AS2.1, not in RH 8.x/9.x
Any bug in glibc?
Any ideas?
Thanks.

-----------[ source code: mystatic.cpp ]------------------
#include <iostream.h>
#include <dlfcn.h>
#include <stdlib.h>
int main()
{
void *pHandle = dlopen("libz.so", RTLD_NOW);
if (pHandle) {
cout << "Successfully Loaded!" << endl;
dlclose(pHandle);
cout << "Successfully UnLoaded!" << endl;
}
cout << "Second Time" << endl;
void *pHandle1 = dlopen("libz.so", RTLD_NOW);
if (pHandle1) {
cout << "Successfully Loaded!" << endl;
dlclose(pHandle1);
cout << "Successfully UnLoaded!" << endl;
}
return 0;
}

Compile using : g++ -g -static mystatic.cpp -o mystatic -ldl
Then run: ./mystatic
Successfully Loaded!
Successfully UnLoaded!
Second Time
Segmentaion Fault
