Would you expect then that calling mark_new_vars_to_rename, like you did in your patch, will fix this problem? I wasn't able to reproduce this error on powerpc-linux and i686-pc-linux-gnu. I do realize that there's a problem with the setting of virtual operands in the vectorizer. The over conservativeness in the vectorizer with respect to setting aliasing information for vector pointers when accessing struct fields may be responssible for this. I will try to look into this issue. In the meantime, could someone that can reproduce this problem try out the mark_new_vars_to_rename patch that Zdenek suggested in the link? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=26197
