-fwrapv is not necessary, just -O2 is enough.
I append a semi-preprocessed file (I removed all of the system headers
and cut out lots of crap before getting tired) that calls for libguile
as well (including the headers of those would have been too much).
As I said: the code generated for
Tab_staff_symbol_engraver::acknowledge_staff_symbol (Grob_info gi)
is the problem, namely its call to
Grob::internal_set_property
where it confuses the second argument with `this', generating the code:
movl %ebx, 40(%esp)
movl %ebx, 32(%esp)
movl %eax, 36(%esp)
addl $24, %esp
.cfi_remember_state
.cfi_def_cfa_offset 8
popl %ebx
.cfi_def_cfa_offset 4
.cfi_restore 3
jmp _ZN4Grob21internal_set_propertyEP17scm_unused_structS1_
Can you take it from there?
Thanks
