Hi Jam,

You might be seeing this crash as c++ support may not there for tracepoint
probes.
Seen this note while going through bugfixes  in 2.7
https://github.com/lttng/lttng-ust/commit/c87d0ff28731aa18660cbb076e69ed7677dea3d2

"- 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)."

But you are seeing this only when using g++ with 32-bit apps. 64-bit apps
compiled g++ dont crash.
Would be good if experts comment here.

Thanks,
Anand Neeli
