[Development] Qt5.2.0/QtCreator3 + GDB 7.6.1-1 problem

Sun Dec 1 15:14:24 CET 2013

  Hi guys , I hadn't used QtCreator and Qt in a week or two and now 
,after I downloaded the RC1, I see that debugging is broken . I tested 
gdb from the command line and it works just fine , but in QtCreator it 
gets stuck on "Setting breakpoints" (or something like that) and there's 
no way to pause the application or to detect segfaults (they get 
reported as a break during startup) , while the app itself starts up 
normally . Here's my debugging output (I've replaced the project dir 
path with ~~~) (my system is manjaro):
