@billyfish
Yeah versions exactly the same as yours.

As for what .md cause crash : just download http://os4depot.net/share/utility/text/edit/vim_mui.lha

There is README.md. Load it, and click "Update" it then crashes in the HTMLview, in the DecoderThreadPC function, with 8x00000003.

Crashlog saying it can't load vimllogo.gif , and assmebler instruction which crashing is "lwz r14,12(r15)", and r14 are 0xFFFFFFFF, and r15 are 0x000000.

There is full crashlog
