Err, t2() -> fun identity/1. -- Anthony Ramine > Le 14 oct. 2013 à 12:45, Anthony Ramine <[email protected]> a écrit : > > Hello Kostis, > > To reproduce the crash, compile the following module with +native with my rm-reverse-eta-conversion branch: > > -module(t). > -export([t1/0,t2/0]). > > t1() -> fun identity/1. > t2() -> fun identity/2. > > identity(X) -> X. > > 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. > > Regards, > > -- > Anthony Ramine > >> Le 8 oct. 2013 à 20:12, Kostis Sagonas <[email protected]> a écrit : >> >> Anyway, I am not sure how to contribute here and it will take me quite some time to investigate this from scratch, time which sadly I do not have these days. 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. > _______________________________________________ erlang-patches mailing list [email protected] http://erlang.org/mailman/listinfo/erlang-patches
