Trying ngx_pagespeed 1.6.29.5 beta on Nginx 1.4.2 in Centos 64bit with GCC 4.7.2 Throws segfault on every web page load, errors loop like this:

Is there anything unusual about your pagespeed or nginx configurations?

Would you be able to compile with --with-debug to get more detailed log messages?

Can you get a backtrace?

jeffkaufman commented 11 years ago

(Looking at the re2 code, the "Unknown encoding 0" error means that re2 doesn't recognize the encoding and is treating it as utf8. I think this is probably an unrelated issue.)

@luctory Could you add this to the http{} block in your nginx.conf file?: pagespeed InstallCrashHandler on;?

Hopefully, a backtrace of the segmentation fault will be logged - if you can capture and post that backtrace of this that would be great .

thanks @oschaaf I did it,and got the next logs.

@luctory It would help if you could you recompile --with-debug and set the error logging level to debug in nginx, and post another capture of the crash, up to and including a few lines before crash. If that isn't possible, your exact nginx version would also be good to know

oschaaf commented 10 years ago

@luctory -- sorry, I see you already have compiled --with-debug. It's hard for me to translate the addresses in the backtrace to line numbers in the source code on my system. Could you post the output of this on your system (you might need to set the -e flag to the correct path to the nginx binary)? This should translate the addresses to line numbers in the source code, and hopefully that gives something easier to work with:

addr2line -e /usr/local/nginx/sbin/nginx 0x804d5ce 0x5bbb11 0x47a4cb 0x5a12a7 0x5a141e 0x592ffe 0x767f33 0x4efd0b 0x72fc11 0x4c7d91 0x5e5fe0 0x4cb26b 0x4b6952 0x5b1a82 0x62670c 0x5b1a82 0x62670c 0x5b1a82 0x62b1b6 0x62cff8
