[Sbcl-devel] scavenge error while porting to NetBSD

[Valtteri V. <vu...@pu...>]

I've been porting sbcl 0.7.9 to NetBSD with the generational GC (I
added the fault address passing functionality into the kernel and
wrote some adapter functions to hopefully make BSD signals look
sufficiently like SIGINFO signals). I have attempted to generate a
cold-sbcl.core both on NetBSD with cmucl and on FreeBSD with the same
version of sbcl. In both cases it results in an error:

This is SBCL 0.7.9, an implementation of ANSI Common Lisp.
[...]
fatal error encountered in SBCL runtime system:
no scavenge function for object 0x08054ed6 @ 0x550dc724 (widetag 0xcc)
There's no LDB in this build; exiting.

The given tag is the same for both builds, and I think the address is
in the same vicinity.

The dynamic space starts at #x55000000. I've tried moving it around,
but this had no effect, the scavenger error still appears around the
same offset. The object id reported is the same in both cases.

Does anyone have suggestions what could be wrong here?
