New error patterns corrupts the compiler's output

[marfi]

Hi Eran and col.,
I'd like to report that new compiler error patterns corrupts output of the compiler/linker in some cases. Here is a sample:

----------Build Started--------

I dont think it is related to the compiler error pattern, but rather to the changes done to the 'build' process launching
I will have a look at this

It is possible but after removing of two new regex patterns and rebuild of the project the problem disappeared.

OK, I am convinced

Can you provide me with a sample project which can reproduce this issue?

I'm just guessing - you are the boss...

Can you provide me with a sample project which can reproduce this issue?

Just checkout the latest version of wxShapeFramework library (svn co https://wxsf.svn.sourceforge.net/svnroot/wxsf/trunk wxSF), remove files "SampleShape.h" and "SampleShape.cpp" from sample project "wxSFSample2" and rebuild the project.

You were probably right: I've got the same problem for simple console application even if new compiler patterns have been removed. Moreover, the corrupted output appears randomly (sometimes it is good, sometimes corrupted). Here are three different outputs I've got on the same project/configuration.

Btw, this bug only occurs on Linux

This issues should now be fixed in SVN trunk.

I tested it and it works fine also for me now. Thanx!
