Program never completed about hashlink HOT 7 CLOSED

What is the source code for the example?

from hashlink.

(or can it be reproduced with a smaller pure Haxe code sample without any lib?)

from hashlink.

@ncannasse I will try to pack repro in 30 minutes for you

from hashlink.

hl-repro.zip
There are hl.hxml and neko.hxml

from hashlink.

The repro is also hanging on my mac running 10.11.6

I'm having the same issue running the mandlebrot test, it gets to pixel (214,1) and hangs in both hl JIT and compiled hlc

Most recent haxe nightly 3fe3fab

I can't reproduce on Windows, I'll have to check on OSX at work this week.

from hashlink.

I've made a PR for the fix and the hl-repro project no longer hangs

It turned out to be the TRAILING_ZEROES macro. On windows it's defined as an inline function whereas on other platforms it's the macro:

#define TRAILING_ZEROES(x)  (x?__builtin_ctz(x):32)

The problem is if x is a ternary expression like a ? b : c then if a is true TRAILING_ZEROES will return a rather than __builtin_ctz(a).

I've changed the macros to inline functions which also prevents x being evaluated twice.

The hang itself occurred in gc_alloc_var - alloc.c:383 bits gets set incorrectly because of the ternary
