Package: gcc-4.6
Version: 4.6.1-1
Severity: normal
File: /usr/bin/gcc-4.6
I first encountered this problem in gcc-4.5; it also exists in gcc-4.6, but
not in gcc-4.4.
I have stripped the source file to be as small as possible while still
exhibiting the bug. Attached is the resulting preprocessor output file
(stripped-bug.i).
Here is the command-line invocation:
% gcc-4.6 -v -save-temps -O -maltivec -Wall -c -o stripped-bug.o stripped-bug.c
Using built-in specs.
