* sysdeps/generic/ldsodefs.h (struct rtld_global): Replace member `bool _dl_initial_dtv_malloced' with `void *_dl_initial_dtv'. * elf/rtld.c (dl_main): Set it to the new dtv for the main thread. * sysdeps/generic/dl-tls.c (__tls_get_addr): When reallocating the dtv, check if it matches _dl_initial_dtv; if so, malloc and copy the old data, abandoning the original memory allocated by rtld at startup, instead of calling realloc normally.
