commit 8cd97deb57777f7f8b690775b8d20d65858b35dc
Author: Christian Schafmeister <meister@temple.edu>
Date:   Thu Jun 20 11:32:05 2024 -0400

    Added a safe function to walk the frame-pointer list on the stack.

Dropping back to previous commit, cb4e391 did not help.

[mgsouth]

Removing --debug-slow fixes things.

[mgsouth]

Fixing the mispelling of "--debug-assert" (thx paulapatience) didn't change anything.

[mgsouth]

I've rolled back to 26179ee, Nov. 2023. Still no good.

../include/clasp/gctools/gcvector.h:268:18: error: invalid operands to binary expression ('StampWtagMtag' and 'int')
  268 |       if (header == 0) {
      |           ~~~~~~ ^  ~

Meanwhile...

src/gctools/include/memoryManagement.h:  struct StampWtagMtag {

I don't think there's ever going to be a commit that will make that equal to 0. Is this a dependency update thing?

I would guess the DEBUG_SLOW code is just bitrotten. That's a pretty bad name for a debug flag and it barely seems to have any code associated with it anyway.
