------- Comment #5 from bonzini at gnu dot org 2009-08-17 08:42 -------
Can you check if the same preprocessed source for deflate.c (the deflate.i file
obtained with --save-temps) compiles fine with both 3.4.0 and 4.4.1? If so,
please attach it together with the deflate.s files produced by the two
compilers (also obtained with --save-temps).
Thanks.
