10.0.17 is affected as well, even though I didn't see it crash (memory corruption caused probably less damage than in 5.5.x).

[ [~serg], I don't have s390x to reproduce, are you (or anybody else) able to do something by the stack trace alone? ] |

| Summary | Segmentation failure when running mysqladmin -u root -p | [PATCH] Segmentation failure when running mysqladmin -u root -p |
I've reproduced it on x86_64 as well, it doesn't seem to be specific to s390x.
Oh you are right, sorry. I ran mysqladmin -uroot -p and it worked okay, but mysqladmin -u root -p crashes.

This is a proposed patch.
I think the issue is caused by working with
temp_argv[-1]item in case argc == 0. The attached patch should hopefully prevent that issue.
