I have no crash with the current nightly, however, DoxyBlocks and ThreadSearch toolbars contains no images. Some images used by FortranProject plugin are not shown too. The problem is that folder "<C::B folder>/share/CodeBlocks/images" does not contain DoxyBlocks, ThreadSearch, fortranproject, wxsmith folders. Manuall copying these folders does help.
my devel31_64\share\CodeBlocks\images does contain them, and each have 3 subdirs containing files.
and indeed :output31_64\share\CodeBlocks\images is missing many subdirs (codesnippets, DoxyBlocks, fortranproject, Threadsearch, wxsmith)
I ran update31_64.bat once more ==> result stays the same ...
