Segfault when building with GCC 8 #232

Closed antonio-rojas closed 5 years ago

antonio-rojas commented 5 years ago

rttr segfaults when called from kdenlive if it's built with GCC8 or Clang 8. Doesn't happen if built with GCC 7

Seems to be a compiler bug - works fine with GCC prior to 8.2.1 and with 8.3 onwards.
