Bug ID: 37986
Summary: Segmentation fault (core dumped) when loading core
dump (armhf on arm64)
Product: lldb
Version: 3.9
Hardware: Other
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: All Bugs
Assignee: lldb-dev@lists.llvm.org
Reporter: anthony.ab...@gmail.com
CC: llvm-b...@lists.llvm.org
I get a Segmentation fault (core dumped) error when loading a core dump for a
program that was hung. I created the core dump using gcore
The process is an armhf (32bit) running on arm64
Easily repeatable, and I have the core dump from lldb if that will help.
Some notes -
OS: armbian
kernel: 4.14.21-sunxi64 (custom)
command: lldb-3.9 -c zcore.dump.32684 /path/to/binary
actual output:
(lldb) target create "/path/to/binary" --core "zcore.dump.32684"
Segmentation fault (core dumped)
process is a .Net core 2.1 application which according to docs requires lldb
3.9 for debugging
------------
I can think of a few things going wrong here (given the types of problems i
have had in the past getting everything else working)
1. kernel / os missing features?
2. lldb running 64bit version instead of 32bit (does it even matter?)
3. user error?
4. lldb bug?
Any suggestions, or help is appreciated!
