+
+That's a very nice catch!
+
+We do not support building tracepoint probe provider with
+g++ yet, as stated in lttng-ust(3):
+
+"- Note for C++ support: although an application instrumented with
+   tracepoints can be compiled with g++, tracepoint probes should be
+   compiled with gcc (only tested with gcc so far)."
+
+However, if it works fine with this fix, then I'm tempted to take it,
+especially because removing the empty union does not appear to affect
+the layout of struct lttng_event as seen from liblttng-ust, which must
+be compiled with a C compiler,  and from probe providers compiled with
+a C compiler. So all we are changing is the layout of a probe provider
+compiled with a C++ compiler, which is anyway buggy at the moment,
+because it is not compatible with the layout expected by liblttng-ust
+compiled with a C compiler.
