Fix intergrated in 1.1.8 for bug#4178309 causes the VM crash, you could
reprodece this bug by trying "demo/applets/awt-1.1/lightweight/gauge".

The fix for bug#4178309 is absolutely incorrect, you need the strdup to get
a copy of fname if the dll is being loaded in successfully (not already loaded,
not "dll not found" or out of memory), because we need put copy of fname into
the dllarray chain for future lookup.
