TTimer::SingleShot fires twice

Dear rooters,
Version: 5.26.00 on ubuntu 910, 64bit.
it seems to me that TTimer::SingleShot fires twice.
Running the att code with

rootcint -f G__dict.cxx -c tsingleshot.h LinkDef.h
g++ -o tt tsingleshot.cxx G__dict.cxx -I$ROOTSYS/include `root-config --libs`
 ./tt

shows this.

Cheers
Otto

Hi Otto,

I’ll have a look.

Cheers, Fons.
