Re: dwz: libsleef3.debug: .debug_line reference above end of section
Hi,
Thanks for the pointers. But I think I'm not able to fix it even if
I tried to diagnose the debug information.
ATM I asked several people and it is likely that the dwz error
stems from toolchain support problem. Now the build log on non-release
archivectures are also available, and it seems that nearly all these
non-release architectures (kind of) suffer from similar prblem.
Temporarily overriding dh_dwz to noop it is an eligible solution to me.
Another solution could be simply downgrading dh compat back to 11.
