[Bug rtl-optimization/33961] New: [4.3 regression] gcc 4.3 causes crash valid code to crash

[bero at arklinux dot org]

The attached simple sample application crashes if it is with g++ 4.3 at -O1 or
higher.

To make things even odder, it works as expected when built with g++ 4.3 at -O1
or higher with -DDONTCRASH, even though the #ifdef DONTCRASH codepath is never
actually run.

The problem is reproducable on both x86_32 and x86_64.


This bug affects KHTML.
