Processes hang inside kernel built with gcc5

[Sasha Levin]

Hi all,

When booting a -next kernel with gcc5 it seems that some processes will hang
on execution, while others will run just fine.

I wasn't able to find exactly what part of the kernel causes this issue, but
I've bisected gcc and found the offending commit:
https://gcc.gnu.org/viewcvs/gcc?view=revision&revision=213753

I've reported this issue to GCC (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63279).


Thanks,
Sasha
