I'm using / testing a git kernel upstream on my hardware (sparc64 /
ppc64 / ia64 ).
Only this time, installing latest git kernel, I get a sigserv on
sparc64 from klibc utility (fstype), and posted about it to mailing
list.
So, to properly report with gdb backtrace, i was need to build klibc
(fstype) with debug info.
I'm not able to fix it myself, so probably someone else could look
into the issue (or i'm just raising awareness for the issue to other
who can hit it as well).
It could be compiler issue as well, if files in klibc.git repo does
not changed for about a year....
I was asking for help with building debug version of klibc and since i
was able to build it, we could close this issue for now (going to
discuss it with debian distribution maintainers first).
Thanks!
