Hi guilers,
Write the following to "crash.scm":
> (call-with-values backtrace list)
> #t
(the trailing #t is important) and run
> # --auto-compile works too, but --no-auto-compile doesn't cause a crash
> guile --fresh-auto-compile -l crash.scm
it will segfault during the printing of the backtrace:
> Backtrace:
> In ice-9/boot-9.scm:
> 1752:10 8 (with-exception-handler _ _ #:unwind? _ #:unwind-for-type _)
> In unknown file:
> 7 (apply-smob/0 #<thunk 7f1390524080>)
> In ice-9/boot-9.scm:
> 724:2 6 (call-with-prompt _ _ #<procedure default-prompt-handler (k
> proc)>)
> In ice-9/eval.scm:
