For the past few days, a clean/fresh build from mozilla trunk (cvs) would produce a mozilla that would crash before opening the first window. The .mozconfig used for the build is: # Options for 'configure' (same as command-line options). ac_add_options --enable-crypto ac_add_options --disable-debug ac_add_options --enable-optimize="-g -O2 -march=i686" ac_add_options --disable-ldap ac_add_options --disable-bidi ac_add_options --disable-tests ac_add_options --enable-reorder Removing the "--disable-debug" will make the browser start up and run. The traceback is as follows: (gdb) run -P [New Thread 1024 (LWP 27470)] [New Thread 2049 (LWP 27492)] [New Thread 1026 (LWP 27493)] [New Thread 2051 (LWP 27494)] Program received signal SIGSEGV, Segmentation fault.

It seems that it is related to the new Type Ahead Find stuff but I don't have time at the moment to track that down.

The only unchecked thing I can see is the QI of chromeEventHandler to nsIDOMEventReceiver. Mike, try adding "if (chromeEventReceiver)" around the two calls that use it at the bottom of nsTypeAheadFind::AttachWindowListeners in extensions/typeaheadfind/src/nsTypeAheadFind.cpp.
I don't see this anywhere in the topcrash talkback data so probably not a blocker.

It seems to only be a problem when the binary is compiled on some of my systems. (Basically, RedHat 7.3 systems) I have not tracked it down due to life conditions getting in the way.
Well, after a long time of playing with this, it finally hit me. (I must have been really slow on this) The difference between my systems that show this problem and the ones that don't is the version of GCC. The GCC 2.95 and GCC 2.96 (RedHat 7.3 GCC 2.96-113) systems show the problem and the GCC 3.1 and GCC 3.2 systems do not. And, even more confusing is that one of the GCC 2.96 systems did not show the problem. It turns out that all of my GCC 2.96 (and 2.95) systems show this problem is if use: ac_add_options --enable-optimize="-O2 -march=i686" If I comment out that setting in my .mozconfig, all is better (well, other that the lack of optimization :-(). So, something in the optimizer produces bad code in Mozilla with the versions of GCC on some of my systems. For this reason, I would say that this bug is no longer a Mozilla bug but a GCC bug. (I guess the best is to mark it as invalid...) BTW - Mozilla used to build just fine before I reported this bug but I got off on another project and then worked mainly on GCC 3.x systems and did not notice when this happened, but I would doubt that it is the fault of any Mozilla code being wrong but rather that something just pushed the wrong parts of the compiler and it broke...
