Source: libunwind
Version: 1.2.1-9
Severity: grave
Tags: patch
Justification: renders package unusable
Dear Maintainer,
* What led up to the situation?
I was running i-g-t on MIPS and hit a segfault during a stack
trace dump.
I then built the package from source to reproduce it, and found a
fix upstream for it (patch attached).

Subject: [PATCH] tdep_uc_addr: use +4 offset for UNW_MIPS_PC on MIPS (be)
According to mcontext_t definition its "pc" field
is also 64 bit wide and thus requires 4 byte offset
on MIPS32 (be).
