SHT_PREINIT_ARRAY/DT_PREINIT_ARRAY/DT_PREINIT_ARRAYSZ is not any kind of extension, it is an integral part of the ELF gABI: http://www.sco.com/developers/gabi/latest/ch5.dynamic.html#dynamic_section And that is quite essential for proper asan behavior, because the library interposes a lot of functions and if they are invoked before the library is initialized, they crash (of course better would be to fix the library not to rely on that and initialize the minimal stuff needed for interposition if they are called before the initialization, but that is unlikely to happen upstream).
