Subject: ld-linux-x86-64 core file SIGSEGV
Date: Sun, 21 Aug 2022 00:37:35 +0100	[thread overview]
Message-ID: <e7d8f49f-f8f9-b60b-745b-b3c14d5736b7@jguk.org> (raw)

Hello
I have a core file from a crash in glibc's ld.so

Couldn't reproduce it. Was just wondering if there was any useful info I could extract to identify which function it crashed in?




I can see the backtrace using 'bt' command.
I can see the assembly using 'layout asm'


Core was generated by `/lib64/ld-linux-x86-64.so.2 /usr/lib/vmware/lib/libvmware-modconfig.so/libvmwar'.
Program terminated with signal SIGSEGV, Segmentation fault.

installing libc6-amd64-dbgsym doesn't show any more


I'm running latest Ubuntu LTS. Just thought I would take a look, see if there is an issue.

$ /lib64/ld-linux-x86-64.so.2 --version
ld.so (Ubuntu GLIBC 2.35-0ubuntu3.1) stable release version 2.35.
