Comment (by kencu):

 the different gcc versions default to slightly different gcc c++ abi
 versions.

 the abi versions are listed here:

 https://gcc.gnu.org/onlinedocs/gcc/C_002b_002b-Dialect-Options.html


 here’s a useful post:

 https://groups.google.com/g/wx-users/c/SQA3DpFwsxA/m/d7J7E4DDBAAJ

 wxwidgets abi checking happens here:

 https://github.com/wxWidgets/wxWidgets/blob/d78b464c5a3e52fee3418b31fff2e4bd73bd3dd0/include/wx/build.h#L59

 and this commit told wxwidgets to ignore all abi changes if the abi was
 greater than 1002:

 https://github.com/wxWidgets/wxWidgets/blob/610db240a8c8c36672f44e34fb0b368b983f1473/include/wx/build.h


 you’ll have to do some further checking to see when that last commit came
 into wxwidgets, and whether the basic idea of it can be backported to
 earlier wxwidgets versions.
