--- Comment #25 from Florian Weimer <fwei...@redhat.com> ---
I applied the patches in attachment 114207 and attachment 114230 on top of the
master branch (commit b9cfb2d15413d16f330878938af3d6fa1617f8b4). I get a crash
in the inline expansion of strlen in ld.so of a z13-enabled glibc build, around
here:
==18364== Invalid read of size 1
==18364== at 0x401892E: _dl_sysdep_start (dl-sysdep.c:236)

(gdb) print/x $r2
$1 = 0x1fff000ffb
(gdb) print (char *)$r2
$17 = 0x1fff000ffb "z13"
(gdb) print _rtld_local_ro._dl_platform
$18 = 0x1fff000ffb "z13"
(gdb) print _rtld_local_ro._dl_platform == $r2
$19 = 1
So strlen is called with the correct value of GLRO(dl_platform), it seems, but
the emulation does not like it.
Are there additional patches I need?
