directory tools/designer/designer uic is used to build a qmake_*.cpp file (image collection) This segv's leaving a partially completed .cpp file.. A repeated make complains of a .cpp without a newline at the end of the file. Reproducible: Always Steps to Reproduce: 1. 2. 3.
I dunno if that's related to your bug but after a major system upgrade (including gcc and glibc), qt-copy (version 3.3.3) also failed to build for me because of a segfaulting uic. I remember that it failed for some uic files somewhere under the designer directory. I was able to build qt-copy after I unmerged the older Qt version. I think somehow the new Qt used the older already installed uic during the build phase on it's newer uic files which resulted in a segfault, but I didn't investigated the issue further.
Yes, if you search for other bugs on this topic it basically says the same thing.
