Hello,
I'm working on the scripting-engine branch of WP, and I keep
encountering a crash. Well, none of you have any experience with this
branch, as I'm its developer, but someone may have an idea about the
crash. My gut feeling is that it's related to boost events or, maybe,
threads (thus, my other post). However, mutexes did not help, as WP
crashes well before them. I hope someone more experienced than me has
seen this before, and can help. Without you, the future of WP's
Scripting Engine is in peril!!
Here's the dump, commented by me. There's a comment BEFORE each
callback. As usual, the callbacks are in reverse order.
//here we are inside a boost lib, this being the last callback, I
guess this is where WP crashes

+ 0x1c bytes
// here we are inside boost, and this is where trouble starts...
