O que causa o patch: **** patch malformado na linha

Question

Eu tenho um arquivo diff que eu criei. Eu tento aplicá-lo em outro ramo com patch -p1 --dry-run < ~/patch_name (eu estou no primeiro diretório - daí -p1 ), mas eu recebo

patch: **** malformed patch at line 45: diff --FILE_LOCATION...

Antes desse erro aparecer, essa linha foi impressa;

checking file file_a
checking file file_b

Então, eu entendo que file_a, file_b estão ok e que eu tenho um problema na linha 45, então eu deletei as linhas 45 para o fim do arquivo (eu fiz isso duas vezes - uma vez sem uma nova linha no final , uma vez com).

Agora o erro é

patch: **** malformed patch at line 44: diff --FILE_LOCATION...

O que há de errado com esse patch?

Este é o patch em si:

Eu criei usando diff , então não entendi como poderia ser malformado ...
