Hello,

You would unpack, configure, and build like you did before (with JIT
enabled, so as to reproduce the crash), but before that you’d run
“ulimit -c unlimited” in that shell to make sure there’s a core dumped
when it crashes.

Once it has crashed, locate the ‘core’ file (or ‘core.*’), and run, say:

  gdb libguile/.libs/guile bootstrap/core

Then from the GDB prompt:

  thread apply all bt

TIA,
Ludo’.
