Bug#503051: gcc-4.2: optimizer produces code that segfaults on Alpha

[Bob Tracy <rct@frus.com>]

Package: gcc-4.2
Version: 4.2.4-3
Severity: important

firefox-3.0.3 builds from the mozilla.org source tree using
gcc/g++-4.2.4 with optimization enabled result in an executable that
segfaults on invocation.  Adding "ac_add_options --disable-optimize"
to the ".mozconfig" file and rebuilding produces an executable that
behaves properly.  Similar bug reports have been filed against the
compiler optimizer for other application builds on 64-bit architectures.
