dovecot - Dec 2014 - v2.2.15 - make check - Conditional jump or move depends on uninitialised value

Hello,

I am currently using Dovecot 2.2.10 on Fedora 16 - 64 bit system

I had made v2.2.10 Fedora 16 rpm file using spec file from ATrpms.
http://dl.atrpms.net/all/dovecot.spec

It has been working well from 6 months or so.

Today I tried to make v2.2.15 rpm using same spec file.

But "make check" is giving following error:

fatal_printf_format_fix .............................................. : ok
0 / 190 tests failed
==8834== Conditional jump or move depends on uninitialised value(s)
==8834==    at 0x4F7FE99: __strspn_sse42 (in /lib64/libc-2.14.90.so)

==8834==    by 0x10FCC9: test_ds_recurse (test-data-stack.c:119)
==8834=
There are more similar errors after that and then rpmbuild aborts.

I already saw that someone reported same error recently:
http://dovecot.org/pipermail/dovecot/2014-October/098452.html

But I do not know what is the right solution / patch?

Can I disable "make check" safely?
Its a production server so would not take any risk.

Can anyone please tell what should I do?

Thanks in advance.

Is it possible that you are encountering this issue?

Either way, the error seems to stem from your libc implementation (if it is not
the valgrind bug).

If possible, upgrade your valgrind, libc etc.

Thank you for reply.

But Dovecot 2.2.10 (and earlier versions) were not throwing this error.

Can I can ignore it by NOT doing "make check"?

OR

is it something serious that if I ignore it can corrupt mailboxes?

Unfortunately for some reasons I can not update libc or valgrind.
