    Description

      If you have an expression that evaluates to a segmentation fault QtCreator ends in an infinite loop, telling you that a segmentation fault happened.
      It happens with GDB 7.11 installed - with 7.6.1 (oldest I could get) this problem didn't occur.

      Steps to reproduce:
      1) checkout recent MuseScore (https://github.com/musescore/MuseScore)
      2) put "mscore->cs->firstMeasure()->segments().first()" as an expression in the expression window
      3) set a breakpoint at beginning of method "TempoText::textChanged()" in libmscore/tempotext.cpp
      4) start debugging
