--- Comment #15 from Kevin Kofler kevin@tigcc.ticalc.org 2009-05-05 09:15:29 EDT --- Hmmm, a lot of things different there: Qt was 4.4.3, it's 4.5.0 in Beta, fontconfig was 2.6.95, was 2.6.99 in Beta and it's also before the mass rebuild with GCC 4.4.
sorry but I didn't get meaning of miscompilation here.
Miscompilation = the C/C++ code gets compiled into invalid assembly due to a GCC bug. If that's indeed what's happening, it'd explain why the same build works on F10.
Has anybody tried using the F10 qt-x11-4.5.0-14.fc10 build on F11 (in particular, with the F11 fontconfig)? That said, I think that won't easily work because OpenSSL has a different soname in F11 than F10.
