+Summary: vbnc.exe crashes in the jit on s390/s390x
+
+vbnc causes the s390 to be crash in the jit, running with gdb I get this 
+native stack trace:
+** ERROR **: Can't handle as return value 0x15
+aborting...
+(...)

+
+This can be reproduced with running only vbnc.exe (and the having the 
+runtime in the same directory available as well).
+
+The s390x is giving a similar stacktrace, however the error is different:
+** (../../class/lib/bootstrap/vbnc.exe:21267): WARNING **: wrong maximal 
+instruction length of instruction break (expected 4, got 22)
+** ERROR **: file mini-s390x.c: line 4200 (mono_arch_output_basic_block): 
+should not be reached
+aborting...
+
+Program received signal SIGABRT, Aborted.

+To repro this it's necessary to check out mono-basic and run make anywhere.
