Greetings,
Have built C::B 12856 using wx3.2.0 on windows 10 (64-bit). Attempting to start it displays 5 asserts (titled "wxwidgets debugging error") sequentially and then closes. Spellchecker update32_64.bat used devel31_64, everything else used devel32_64. Could Spellchecker update32_64bat, that had been renamed from update31_64.bat, be causing the asserts? That update dealt with images.
Regards
