RTLD_DEEPBIND fixes this problem using a test program and two minimalistic DSOs to emulate the namespace clash problem. But I see PHP has support for RTLD_DEEPBIND:
# if defined(RTLD_GROUP) && defined(RTLD_WORLD) && defined(RTLD_PARENT) ... # elif defined(RTLD_DEEPBIND) ... # else ... # endif On my Linux glibc 2.3 systems RTLD_DEEPBIND is chosen. So now, I have to wonder why my customer had a problem in the first place. Based on the above macros, is it possible that RTLD_DEEPBIND could NOT be chosen?
