I don't think so. Here's my complete reading of the stack (where each explanation applies to the frames immediately above): > #0 0x00000000005655b6 in GC_clear_stack_inner (arg=0x0, > limit=0x7fff2dd5ce30 <Address 0x7fff2dd5ce30 out of bounds>) at ./misc.c:243 > #1 0x00000000005655cb in GC_clear_stack_inner (arg=0x0, > limit=0x7fff2dd5ce30 <Address 0x7fff2dd5ce30 out of bounds>) at ./misc.c:245 > #2 0x00000000005655cb in GC_clear_stack_inner (arg=0x0, > limit=0x7fff2dd5ce30 <Address 0x7fff2dd5ce30 out of bounds>) at ./misc.c:245 > [[...SAME...]] > #7 0x00000000005655cb in GC_clear_stack_inner (arg=0x0, > limit=0x7fff2dd5ce30 <Address 0x7fff2dd5ce30 out of bounds>) at ./misc.c:245 > #8 0x00000000005655cb in GC_clear_stack_inner (arg=0x0, > limit=0x7fff2dd5ce30 <Address 0x7fff2dd5ce30 out of bounds>) at ./misc.c:245 > #9 0x00000000005655cb in GC_clear_stack_inner (arg=0x0, > limit=0x7fff2dd5ce30 <Address 0x7fff2dd5ce30 out of bounds>) at ./misc.c:245 > > #10 0x000000000056564b in GC_clear_stack (arg=0x0) at ./misc.c:291 > #11 0x000000000056db58 in GC_generic_malloc_many (lb=2, k=0, > result=0x7e7780) at ./mallocx.c:421 In a GC triggered by... > #12 0x000000000056e3f5 in GC_malloc_atomic (bytes=16) at > ./thread_local_alloc.c:219 ... an allocation request from ... > #13 0x000000000055ee7a in scheme_make_char (ch=12985) at ./char.c:146 > #14 0x00000000005606a4 in integer_to_char (argc=1, argv=0x7fff2c5b7028) > at ./char.c:248 `(integer->char 12895)', probably (assuming that gdb isn't lying), which was called from deep in some expression ... > #15 0x00000000004452b8 in scheme_do_eval (obj=0x909110, num_rands=1, > rands=0x7fff2c5b7028, get_value=1) at ./eval.c:8825 > #16 0x0000000000444bac in scheme_do_eval (obj=0x908ea0, num_rands=<value > optimized out>, rands=0x7fff2c5b7030, get_value=1) at ./eval.c:9416 > #17 0x00000000004449ac in scheme_do_eval (obj=0x7fff2c5a6ba0, > num_rands=4, rands=0x7fff2c5b7010, get_value=1) at ./eval.c:9538 > > #18 0x0000000000444af7 in scheme_do_eval (obj=0x900dd0, num_rands=<value > optimized out>, rands=0x7fff2c5b7058, get_value=1) at ./eval.c:9509 > #19 0x0000000000444af7 in scheme_do_eval (obj=0x900dd0, num_rands=<value > optimized out>, rands=0x7fff2c5b7098, get_value=1) at ./eval.c:9509 > #20 0x0000000000444af7 in scheme_do_eval (obj=0x900dd0, num_rands=<value > optimized out>, rands=0x7fff2c5b70d8, get_value=1) at ./eval.c:9509 > [[...SAME...]] > #173 0x0000000000444af7 in scheme_do_eval (obj=0x900dd0, > num_rands=<value optimized out>, rands=0x7fff2c5b8dc8, get_value=1) at > ./eval.c:9509 > #174 0x0000000000444af7 in scheme_do_eval (obj=0x900dd0, > num_rands=<value optimized out>, rands=0x7fff2c5b8e00, get_value=1) at > ./eval.c:9509 > #175 0x0000000000444af7 in scheme_do_eval (obj=0x900dd0, > num_rands=<value optimized out>, rands=0x7fff2c5b8e40, get_value=-1) at > ./eval.c:9509 > #176 0x000000000044218a in scheme_enlarge_runstack (size=<value ...
