> Loading this module compiled with HiPE on my branch will make HiPE crash in patch_funentries. Commenting the t2/0 function out makes the crash disappear. That shows that the cause of the crash is multiple references to the same local function.

I can spend some time on this if I feel like hacking again one of the nights to come, but only if you minimize this and send me a self-contained module that shows the problem when you generate BEAM code with the changed compiler, but not with the vanilla.
