> Hi,
>
> When I am improving my patchset to discard unused branches of tunable
> conditionals these days, I run into a new segfault issue that seems has
> nothing to do with my patchset. After I checked back to the master branch
> for both toolchain and refpolicy and pulled the latest codes, the segfault
> still exist.
>
> Turns out the problem lies in genhomedircon.c, the level argument passed to
> set_fallback_user is NULL, and strdup(NULL) would segfault in the end. Below
> is the debug message I've seen:
>
> genhomedircon.c Entered set_fallback_user, user = user_u, prefix = user,
> level = (null)
> Passing NULL to strdup would segfault
> make: *** [load] Segmentation fault
>
> Has anyone else also run into the same problem? I didn't run into it before
> Aug 23rd, if this is a real problem, then it must have been introduced after
> that date.
>
> So far I am pretty new to the semanage code, any idea to fix this issue?

> Thanks,
