Bug ID: 104207
Summary: [12 Regression] Crash in _Unwind_Find_FDE if object
lacks unwind information
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libgcc
Assignee: unassigned at gcc dot gnu.org
Reporter: fw at gcc dot gnu.org
Target Milestone: ---
Build: *-*-linux-gnu
r12-6210 lacks a NULL check for dlfo_eh_frame. This causes crashes when
unwinding through signal frames if the kernel vDSO has not been built with
debuginfo.
