Both of these free() calls are freeing a "const unsigned char (*)[20]" type while free() expects a "void *". This results in the following warning under clang 2.9: builtin/diff.c:185:7: warning: passing 'const unsigned char (*)[20]' to parameter of type 'void *' discards qualifiers free(parent); ^~~~~~ submodule.c:394:7: warning: passing 'const unsigned char (*)[20]' to parameter of type 'void *' discards qualifiers free(parents); ^~~~~~~ This free()-ing without a cast was added by Jim Meyering to builtin/diff.c in v1.7.6-rc3~4 and later by Fredrik Gustafsson in submodule.c in v1.7.7-rc1~25^2.
