            Bug ID: 45105
           Summary: Parsing an inconsistent .eh_frame section cause crash.
           Product: libraries
           Version: trunk
          Hardware: All
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: DebugInfo
          Assignee: unassignedbugs at nondot.org
          Reporter: ikudrin at accesssoftek.com

DWARFDebugFrame::parse() issues report_fatal_error() on any problem it founds,
which leads to aborting the program and generating a crash report, see
test/DebugInfo/X86/eh-frame-cie-id.s test in https://reviews.llvm.org/D73886 as
an example.

Parsing methods are expected to be more tolerant. They should continue parsing
in case of recoverable errors or just return an Error when encountering
something unrecoverable.
