Re: [webkit-dev] jsc bus error EXC_BAD_ACCESS with jsc-only build on Mac

2024-04-22 Thread Keith Miller via webkit-dev 
Hi folks, 

Looks like this happened during our adoption of the BrowserEngine API. I have a 
PR to fix it https://github.com/WebKit/WebKit/pull/27587

There was also an unrelated build breakage for the JSCOnly port, which I also 
fixed in that PR.

Cheers,
Keith

Hi,

Hi, I’m trying to build jsc on my M1 Mac following the instructions at
https://trac.webkit.org/wiki/JSCOnly and https://webkit.org/getting-started/ .
However when I run the built binary it exits immediately with a bus error
which lldb shows to be EXC_BAD_ACCESS.
I'm also trying to build JSC on my M1 Mac and my experience is the exact same 
error as Laurence has reported above.

When I run I get a bus error at the same location in the code:
