                    and under GDB only)

            Status: NEW
          Severity: Normal
          Priority: P5 - None
         Component: debug

assembly causing the abort

note: MONO_XDEBUG is not defined in my environment variables - I suspect this
gets called only under GDB since the SIGABRT is different when executed without
gdb


gdb --args mono --security=core-clr --compile-all
bin/System.ServiceModel.Web.sigabrt.51027.dll
