+Summary: ARM build (and others) broken
+
+The JIT build for arm (and probably amd64/arm/sparc/itanium) is broken:
+
+gcc -I../.. -I../../libgc/include -I/usr/include/glib-2.0
+-I/usr/lib/glib-2.0/include -I/usr/include/glib-2.0
+-I/usr/lib/glib-2.0/include -g -O2 -fno-strict-aliasing

+`mono_print_thread_dump':

+reference to `mono_arch_sigctx_to_monoctx'

+
+Only exceptions-x86.c implements the sigctx->monoctx call, but ppc defines
+CUSTOM_STACK_WALK so the issue isn't apparent on x86 or ppc.
+
+Some more thoughts from ever-resourceful kangaroo:
+
+[05:44] <kangaroo> well the problem is his check
+[05:44] <kangaroo> we should do something like
+[05:44] <kangaroo> #ifndef CUSTOM_STACK_WALK && defined
+(MONO_ARCH_HAS_CONTEXT_CONVERTER)
+[05:44] <kangaroo> or some such
+[05:44] <kangaroo> and define that on platforms that do
+[05:45] <kangaroo> the big thing you need to set in that convert
+[05:45] <kangaroo> convertor
+[05:45] <kangaroo> for the method in question to work
+[05:45] <kangaroo> is the bp
+[05:46] <kangaroo> which is the esp
+[05:46] <kangaroo> which is ARMREG_SP
+[05:47] <kangaroo> which would be sigctx->arm_sp;
+[05:47] <kangaroo> so
+[05:48] <kangaroo> struct sigcontext *ctx = (struct sigcontext *)sigctx;
+[05:48] <kangaroo> mctx->esp = ctx->arm_sp;
+[05:48] <kangaroo> _should_ be sufficient
+[05:48] <kangaroo> for you to a) compile; and b) have working thread dumping
