Do you know of any Scheme using libgccjit?
BTW, I tried to build mainline with --enable-coverage to see which code
is executed with -foptimize-sibling-calls, but bootstrap fails with

Perhaps there's a case for a frontend attribute for this.

Perhaps "incorrect" was the wrong word. If sibling-call optimization is
not done, then perhaps the program will blow out the stack, which would
not happen if the opt
The Gambit Scheme->C compiler has an option to generate more efficient
code if it knows that all tail and sibling calls in the generated C code
will be optimized. If gcc does not, however, optimize a tail or sibling
call, the generated C code may be incorrect (depending on circumstances).
So
