Reproducible SIGSEGV when Dovecot 2.3 compiled against glibc-2.28

[Thore Bödecker]

Hey,

you mentioned that dovecot builds fine, but does "make check" also
complete successfully with a glibc-2.28 build on a glibc-2.28 system?

We have been seeing segfaults during "make check" and it seems the following
patch was able to make the testsuite run successfully.

Just out of curiosity, could you try this patch and see if this fixes
the issues you're experiencing?


include-crypt-h.patch:
