I tried to upgrade my passenger+nginx install to passenger 3.0.11 on our  
staging server to match our production server, I’ve also upgraded to  
ruby 1.9.3. Previously I had successfully run passenger 3.0.3 with ruby  
1.9.2.

After installing the new passenger gem 9.0.11, I install as usual using  
passenger-install-nginx-module. Everything seems to build without any  
problems but when I try and do:

/opt/nginx/sbin/nginx -V

I get “Segmentation fault”, when I look in the log file I have:

Apr 19 19:00:28 jbdev1 kernel: nginx[32336]: segfault at 705740 ip  
0000000000705740 sp 00007fff4673f478 error 15 in nginx[6f5000+11000]

I’ve tried building with the latest version of passenger 9.0.12 but I  
get the same problem. I’ve installed passenger+nginx many times on many  
server without this problem.

I’m running this particular build on suse linux

Linux jbdev1 2.6.27.19-5-default #1 SMP 2009-02-28 04:40:21 +0100 x86\_64  
x86\_64 x86\_64 GNU/Linux  
SUSE Linux Enterprise Server 11 (x86\_64)  
gcc version 4.3.2 [gcc-4\_3-branch revision 141291] (SUSE Linux)

Any help appreciated.

Etienne.

Ran gdb with a backtrace and got the following, is there an incompatible  
library or something?

Program received signal SIGSEGV, Segmentation fault.
