Bug 132378 – [4.1/ICE] vim 7 ICE using -ftree-vectorize -Os -maltivec

• Status: RESOLVED WONTFIX
• Product: Gentoo Linux

[Description Diego Elio Pettenò (RETIRED) 2006-05-05 13:37:49 UTC]

I hit this little problem on my iBook, vim 7 beta doesn't build when using gcc 4.1.0 and -ftree-vectorize.

As JoseJX tried, the problem lies directly in -ftree-vectorize, because adding it on his setup broke vim with the same error.

Confirmed and reducing.

[Comment 3 Mark Loeser (RETIRED) 2006-05-15 17:00:54 UTC]

This is fixed in 4.1.1, which will be out in the next few days, so there is no point in backporting this.

helps to actually change the status of the bug...
