I'm getting the similar bug from last 3.10.1 version: I: A function overflows or underflows an array access. This could be a real error, but occasionaly this condition is also misdetected due to loop unrolling or strange pointer handling. So this is warning only, please review. W: claws-mail arraysubscript sspm.c:406
Created attachment 1413 [details] implicit declaration elimination patch As claws-mail-3.10.1 build log still contains last implicit declaration warning: src/plugins/vcalendar/libical/libical/icalderivedproperty.c:374:4: warning: implicit declaration of function ‘icalproperty_add_parameters’ [-Wimplicit-function-declaration] I propose patch that fixes that warning.
