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,
