["dominiq at lps dot ens dot fr" <gcc-bugzilla at gcc dot gnu dot org>]

------- Comment #16 from dominiq at lps dot ens dot fr  2007-11-29 08:06 -------
A quick report of the comparison between the regression results for revision
130500 + patch in comment #5 + Tobias' patch for pr34262 and revision 130489 +
some patches applied to rev. 130500. I have the following new failures:
