--- Comment #25 from lvying <lvying.system.thoughts at gmail dot com> ---
Hi, when I use Szabolcs Nagy's comment 2 comment 3, I got Assertion:
Inconsistency detected by ld.so: dl-tls.c: 517: _dl_allocate_tls_init:
Assertion `listp !=3D NULL' failed!
Also, I try this testcase pacth:
https://patchwork.ozlabs.org/project/glibc/patch/5836CC80.9070101@arm.com/
After I put patch the patch into the glibc code, and run nptl testcase, I g=
ot:
../scripts/evaluate-test.sh nptl/tst-tls7 $? false false >
/root/build/build/glibc/nptl/tst-tls7.test-result
Inconsistency detected by ld.so: dl-tls.c: 517: _dl_allocate_tls_init:
Assertion `listp !=3D NULL' failed!

Both of the testcases got different assertion, not the assertion:
Inconsistency detected by ld.so: dl-tls.c: 493: _dl_allocate_tls_init:
Assertion `listp->slotinfo[cnt].gen <=3D _rtld_local._dl_tls_generation' fa=
iled!

So, how to reproduce this problem to get the same failure.
And is there a plan to solve this problem? This problem has been going on f=
or a
long time.

Thanks!
