do you know why the actual segfault is happening? is it longjmping to an expired buffer?

the slime thing was weird in that it would segfault, but then i could resume from _that_ and continue using the slime repl normally

There are a whole bunch of sjlj_unwind's one after another and then it fails on one.

i did a quick survey of interpreted gf calls, since i have the compiler totally disabled, and man is the distribution skewed

if you take only functions that have actually been called, it's 504,926 and 9490 respectively

man, so if compiling it shaves a millisecond from each all, that's twenty five seconds... which sounds impressive until you remember how slow the compiler is

this is why i mentioned compiler coordination earlier- as is there's very little, but if you want to keep doing this kind of debugging it'll make things a lot less painful

I printed the DynEnv stack on the left at the start of the sjlj_unwind and the DynEnv stack after the first proceed.

also, i wonder if we should find some way to coalesce bindings, but that's not important

This is the backtrace for the TagbodyEnv destination - the same function (of course)

This is on the stack when the UnwindProtect that it unwinds to is put on the stack
