I'm trying to use gsc to build a shared library, but I'm having issues. I've been through the info file and tried a host of build techniques, and while the library compiles fine when I try to use it my test executable segfaults somewhere in __garbage_collect(). I've pared it to a trivial situation: library.scm: (define (hello) (display "hello") (newline)) (c-define (c-hello) () void "hello" "" (hello)) Makefile: gsc -link library gsc -obj -cc-options "-D___SHARED" library.c library_.c gcc -shared -o liblibrary.so library.o library_.o \ -L/home/evanhanson/.builds/gambc/lib -lgambc test.c: int main(int argc, char* argv[]) { hello(); return 0; } And the backtrace from gdb: #0 0x00007ffff782ea09 in ___garbage_collect () from ./libgambc.so #1 0x00007ffff782fbcc in ___alloc_scmobj () from ./libgambc.so #2 0x00007ffff782fd3b in ___make_vector () from ./libgambc.so #3 0x00007ffff78325ca in ___make_sfun_stack_marker () from ./libgambc.so #4 0x00007ffff741ce94 in hello () from ./libom.so #5 0x000000000040064d in main () I'm sure there's something simple I'm missing. Any suggestions? Evan
