I think I've broken the rules on thread affinity somewhere in my Qt C++ application.
I'm getting lots of messages like this:
QBasicTimer::stop: Failed. Possibly trying to stop from a different thread
QBasicTimer::start: Timers cannot be started from another thread
I am using DDD/GDB. Can I insert some kind of trap which will catch these errors and give me a backtrace? Ideally suspending all other threads in the meantime?
I tried to halt on writing to stdout (b write if 1==$rdi as per this) but that didn't work.
