What does the following segmentation fault mean?

Fatal error (11)Segmentation fault
What is a segmentation fault, and what can cause it to happen?

The issue arrises once I type, Mx gdb into Emacs,

the scenerio is descirbed as the following picture shows:
a) input command to enter gdb mode
http://i1271.photobucket.com/albums/jj624/bigmeowOoO/before-enter-gdb...

b) press Enter to enter gdb mode, then error appears
http://i1271.photobucket.com/albums/jj624/bigmeowOoO/after-i-press-en...

more details:

[a]: i build emacs 24.1 on centos 5.3 from source, this build cannot enter gdb mode

[b]: also i build emacs 24.1 on debian 5.0, it can use gdb mode without error

so i really don't know what happened that i cannot use gdb mode in emacs 24.1 on centos 5.3:(

Hi,

To get more information run emacs under gdb:

- cd src
- gdb emacs
- r (shorthand for run)
- reproduce the bug M-x gdb
- you should enter the debugger when you segfault
- bt full (copy the output, I use screen to do that)
- M-x report-emacs-bug

I forgot to tell you on #emacs, I don't think you should compile emacs
with nox.

HTH
