Jeffrey A. Law <law at redhat dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |law at redhat dot com --- Comment #4 from Jeffrey A. Law <law at redhat dot com> --- I'd be real surprised if that commit was the real cause. It's more likely exposing a latent issue. Note that the two list implementation changes the order in which SSA_NAMEs are reused, which in turn can change coalescing decisions. Normally I'd push this to P4, but leaving it as a P3 until at least enough analysis is done to know if it's really a problem with tpcs-leaf-frame or exposing a deeper problem elsewhere that might be critical to fix.
