Segfaults on last git version

crisidev commented 7 years ago

I guess this is related to the Os vs O2 optimization, but last git version (a746b3451fe1e811f490df6f30d29250be284a65) is segfaulting:

skhd: using config '/Users/bigo/.skhdrc'
(#2) hotkey :: {
    mod: 'cmd'
    mod: 'alt'
    key: 'q' (0x0c)
[1]    98392 segmentation fault  skhd

I assume this is still installed using homebrew?

I can reproduce this with the homebrew install, but I cannot reproduce the problem by building manually with -0s. Prior to the fix in #7, I could reproduce with -0s. This makes me think the hmoebrew build settings differ in other aspects than just the optimization level.

I'm going to try and override the homebrew formulae to build with -03 and if that does not fix it, I will be removing the homebrew option.

This is just stupid; e.g https://github.com/koekeishiya/skhd/commit/e1e8a631ad6e312ba6e446b0f8adcf815c0fab70 this change fixed the segfault in #7.

These issues seems to be caused by aggressive compilation settings, and it is not something I can reliably debug as it is directly connected to the compilers code generation.

Updated homebrew formulae.

I can confirm, v 0.0.10 work fine. Thanks for the quick fix.

As much as I want to avoid reopening this Issue......

skhd: using config '/Users/snwFlake/.skhdrc'
(#34) hotkey :: {
    mod: 'alt'
[1]    50367 segmentation fault  skhd

Sierra 10.12.6
Homebrew 1.3.5
skhd 0.0.10
clang 800.0.42.1 (xcode) | clang standalone 6.0.0-pre
no gcc installed

Same with -O2 and -O1

Edit: Has to be brew related, building the source works like a charm.... So +1 for removing the formular
