GNU在Ubuntu-20.04上制造3.82运行时错误:分段错误(内核转储)

Question

我从GNU下载了gnu-mak-3.82，并在我的Ubuntu-20.04机器上的一个特定目录(例如dir)上制作和安装它。

然后我跑了

$file dir/make

它返回：

ELF 64位LSB共享对象，x86-64，version 1 (SYSV)，动态链接，解释器/LSB 64/ld-Linux-x86-64.so.2，BuildIDsha1=ef2934bdbc32938713fd4cb1c9a733e8b6785af0，for GNU/Linux3.2.0，带有debug_info，没有剥离

当我跑的时候

$dir/make --version

它返回：

当我使用最简单的Makefile运行它时，它会生成错误：

分段故障(堆芯倾弃)

为什么？我还需要做哪些额外的工作才能使它正常工作？

根据@steeldriver的提示，我对dir.c做了以下更改。

diff --git a/dir.c b/dir.c
index adbb8a9..c343e4c 100644
--- a/dir.c
+++ b/dir.c

   gl->gl_closedir = free;

   gl->gl_stat = local_stat;
-  /* We don't bother setting gl_lstat, since glob never calls it.

 }

然后重新制作并运行它。它可以正常工作，没有任何警告或错误。
