Installed lnav with linuxbrew and got Segmentation fault

What were you doing when it crashed, just opening a file? Does it only happen for certain files?

What OS version were you using?

Can you run 'lnav -d /tmp/lnav.err' to generate a log dump and attach that file? It contains a lot of versioning and other information that would be useful in helping debug the issue.

thanks!

@tstack 

CentOS release 6.3 (Final)
Linux ... 2.6.32-504.16.2.el6.x86_64 #1 SMP Wed Apr 22 06:48:29 UTC 2015 x86_64 GNU/Linux

lnav -d /tmp/lnav.err also causes segmentation fault. btw I compiled lnav from sources on my own and made it work. For some reason linuxbrew version is failing.

tstack commented 9 years ago

I think a log file would still have been generated even when it crashed, can you check and attach it?

@tstack you are right

@tstack I have tried to reproduce this issue on another machine and I could not. So don't want to waste your time, it is some local issue. I could build it without using linuxbrew. So I am fine now.

Thank you for the great tool. I am going to close this ticket.
