I think the deal with hidden PLTs is that fopen() cannot be trapped by an alternate implementation of fopen() inside the LD_PRELOADed library. But the system call open performed inside the libc's fopen() (no matter how it was compiled) should get intercepted by the LD_PRELOAD library. Because I dont think the PLT optimizations would apply to system calls. With regard to the original question, I dont foresee any major problems, but we have not QA'ed this configuration. We would like to hear if you face any problems. Avati
