git のソースに対して同様の処理を試したところ、 core ファイルを取得できました。
以下に事象の再現手順を示します。何か手がかりが得られそうでしょうか？
(1) 普通にコンパイルする。
----------------------------------------
# git clone git://github.com/ruby/ruby.git
# cd ruby/
# autoconf
# ./configure
# make
----------------------------------------
(2) 以下のパッチを当てて再コンパイルする。
----------------------------------------
# patch -p1
