Hello everyone , I use CMake to build a qt4 project,
I found after this commit
ec85306025ae787e08d4ce097fde966f1809c74f
Merge topic 'tll-includes-defines'
re-run cmake of my project gives segmentfault.
console :
....config step is just all right
-- Configuring done
segmentfault
gdb trace the problem here:

the dagChecker is NULL.
hopes this can help. thank you
