Qt 4.8.0 Signal does not act like a Qt::DirectConnection

wamo

Hi,

i switched to Qt 4.8.0 and downloaded the libraries from the homepage.

Since then my code does not act like a DirectConnection although its definitive in the same thread and i forced this behaviour with Qt::DirectConnection as the fourth parameter.

I use the 2010 Libraries. Unfortunately after "qmake -tp vc -r" all of my projects had an optimization flag "/O2" in debug mode?!?

Now if i let this flag then the connection works as expected but i loose many debug features because some breakpoint positions were optimized away.

Any idea?

Remove the optimization flag and recheck? Btw, some bugs were fixed in the connection handling code in 4.8. Could you paste a simple testcase?

If i remove /O2 then the Qt::DirectConnection do not work anymore.

There seems to be a lot of broken things in VS2010 while 4.8.0 was introduced.
