--- Comment #16 from lucier at math dot purdue.edu ---
I have figured out how to build and then run the app in lldb to reliably
reproduce the error.
To configure and build Gambit, the Scheme->C compiler:
51 8:56 mkdir gambit-test
52 8:56 cd gambit-test
53 8:56 git clone https://github.com/gambit/gambit.git
54 8:57 cd gambit
55 9:00 ./configure 'CC=/usr/local/gcc-10.3.0/bin/gcc -save-temps -g'
'--enable-single-host' '--enable-shared'
56 9:01 make -j12
After a few minutes the "make -j12" should end with the message:
*** to compile the builtin modules you should: make modules
Then in the same directory I ran a command to just print the version number and
configuration information of Gambit; I ran the interpreter gsi instead of the
compiler gsc:
[Bradleys-Mac-mini:~/programs/gambit-test/gambit] lucier% lldb gsi/gsi
(lldb) target create "gsi/gsi"

Target 0: (gsi) stopped.
This is my first time running lldb, so I'm a bit slow.
To your other questions: It's not JIT-generated code, and I'll work on building
a mainline compiler to test it, too.
Hope this helps.
