Hi Waldemar,
I have looked into the OpenADK uclibc-tests segmentation fault at hand.
Although, I haven't fully tested the patch I think it is a fix for the
issue.
Considering how long I took to look into this problem, I decided to
provide you a patch immediately for you to try it.
BTW, in my case, it fails a little further, but because of some
undefined references.
Maybe it is not really a problem on the toolchain.
Best regards,
Cupertino

I have yesterday seen this
commit
c579f48edba88380635ab98cb612030e3ed8691e in glibc and would
like to follow here and remove any PID/TID caching.
Afterwards I can take a look into 0cb313f7cb0e41.
I reported the issue to Alexey last year.
We added your binutils maintainer to the thread.
Yesterday he had again time to reproduce the problem, but there was
some missing information I gave him yesterday.
So may be you can help with this?
It is beyond my area of expertise and Cuper is
looking into it, it is in good
hands already ;-)
OTOH the reason I was dabbling into this was to track down tst-getpid2 failure on
ARC as reported in last known reports.
It seems glibc dropped this test and added a new one instead. See commit
0cb313f7cb0e41 ("Fix clone (CLONE_VM) pid/tid reset (BZ#19957)")
I tried copying over tst-clone2 into uClibc (with a hdr include adjustment), but
it seems to runtime fail for me very early (atleast in nSIM).
| [ARCLinux]# ./tst-clone2
| child pid (62) != received pid/tid (0/1606237724)
| parent pid (61) != received pid/tid (0/1606237724)
| [ARCLinux]# random: crng init done
| echo $?
| 2
Can you please double check this for other targets ! It is
really blocking any complete regression testing :(
I know sucks, lets hope Cuper
nails it down quickly.
