#5 export_troff (bytes=0xffffd438, cv=0x56564ae0) at codec/export.c:1056
Dear Maintainer,
this crash happens because the array ansi2troff has
just 16 values, but gets accessed at value 32.
This value 32 originates from the constant CACA_TRANSPARENT.
With the below patch the crash could be avoided.
Kind regards,
Bernhard
