Hi Werner,There are two new warnings from building 2.10.4 on current fedora. One is likely from the newer gcc 11: src/base/ftlcdfil.c:360:42: warning: argument 2 of type ‘FT_Vector *’ {aka ‘struct FT_Vector_ *’} declared as a pointer [-Warray-parameter=] 360 | FT_Vector* sub ) | ~~~~~~~~~~~~^~~ include/freetype/ftlcdfil.h:314:42: note: previously declared as an array ‘FT_Vector[3]’ {aka ‘struct FT_Vector_[3]’} 314 | FT_Vector sub[3] ); | ~~~~~~~~~~~~^~~~~~
gcc 11 has started doing more checks when functions are defined as taking arrays of a given length, which may help catch more buffer overflows: https://developers.redhat.com/articles/2021/06/25/use-source-level-annotations-help-gcc-detect-buffer-overflows#array_function_parameters -- -Alan Coopersmith- alan.coopersm...@oracle.com Oracle Solaris Engineering - https://blogs.oracle.com/alanc
