Mingw build using dwarf2 exceptions?!!!
I installed Qt 4.6.3 libraries (mingw build) from Qt web site.
As I understand they are compiled to use dwarf 2 exceptions instead of sjlj exceptions. However, dwarf 2 exceptions are not portable under windows. Will the exception mechanism be changed in the future releases?
Qt has no direct influence on that. The choice of throwing dwarf exceptions is made at MinGW:
From their "release notes":http://sourceforge.net/project/shownotes.php?release_id=691876
- NEW FEATURES SINCE MINGW GCC 3.4
- Zero cost exceptions: New exception model Dwarf only has performance penalty when being thrown. The old model, SJLJ, is no longer available.
