Comment (by daniel at lorch.cc):

 I can reproduce this problem with OS X Leopard. My solution was to open
 the file

 {{{
 /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_devel_mono/work/mono-1.2.6/libgc/darwin_stop_world.c
 }}}

 by hand and jump to line 106. I removed the whole block enclosed by

 {{{
   #if defined(_STRUCT_X86_EXCEPTION_STATE32)
         lo = state.__esp;

         GC_push_one(state.__eax);
         GC_push_one(state.__ebx);
         GC_push_one(state.__ecx);
         GC_push_one(state.__edx);
         GC_push_one(state.__edi);
         GC_push_one(state.__esi);
         GC_push_one(state.__ebp);
   #elif
 }}}

 It seems to work with the following code:

 {{{
         lo = state.esp;

         GC_push_one(state.eax);
         GC_push_one(state.ebx);
         GC_push_one(state.ecx);
         GC_push_one(state.edx);
         GC_push_one(state.edi);
         GC_push_one(state.esi);
         GC_push_one(state.ebp);
 }}}

 Of course then you'll just run into the next problem:

 {{{

 }}}

 Then I opened mono/mini/mini-x86.h and deleted the block

 {{{
 #elif defined(__APPLE__) && defined(_STRUCT_MCONTEXT)
         #define UCONTEXT_REG_EAX(ctx) ((ctx)->uc_mcontext->__ss.__eax)
         #define UCONTEXT_REG_EBX(ctx) ((ctx)->uc_mcontext->__ss.__ebx)
         #define UCONTEXT_REG_ECX(ctx) ((ctx)->uc_mcontext->__ss.__ecx)
         #define UCONTEXT_REG_EDX(ctx) ((ctx)->uc_mcontext->__ss.__edx)
         #define UCONTEXT_REG_EBP(ctx) ((ctx)->uc_mcontext->__ss.__ebp)
         #define UCONTEXT_REG_ESP(ctx) ((ctx)->uc_mcontext->__ss.__esp)
         #define UCONTEXT_REG_ESI(ctx) ((ctx)->uc_mcontext->__ss.__esi)
         #define UCONTEXT_REG_EDI(ctx) ((ctx)->uc_mcontext->__ss.__edi)
         #define UCONTEXT_REG_EIP(ctx) ((ctx)->uc_mcontext->__ss.__eip)
 }}}

 and replaced

 {{{
 #elif defined(__APPLE__) && !defined(_STRUCT_MCONTEXT)
 }}}

 by

 {{{
 #elif defined(__APPLE__)
 }}}

 To summarize, it seems that the switches _STRUCT_X86_EXCEPTION_STATE32 and
 _STRUCT_MCONTEXT don't have the right values for OS X Leopard.
