无法使用 genhtml 合并覆盖率数据
我正在使用 genhtml （在 Windows 中的 cygwin 下）从 2 个覆盖率数据文件生成单元测试覆盖率报告。它们都是来自同一单元测试源文件的覆盖率数据。
但是，当我输入以下命令时：
perl genhtml /home/administrator/coverage1.dat /home/administrator/coverage2.dat
我得到以下输出和问题：
Reading data file /home/administrator/coverage1.dat
Reading data file /home/administrator/coverage2.dat
genhtml: Can't use an undefined value as a HASH reference at genhtml line 1506.
并且它无法生成任何内容。
我研究了这些文件，发现原因之一可能是覆盖数据中重复的标头和文件。
这是一个已知问题，或者有人知道解决它的方法，还是我走错了路？
谢谢。
I'm using genhtml (in Windows under cygwin) to generate a unit test coverage report from 2 coverage data files. They are all coverage data from the same unit test source file.
However, when I entered the following command:
perl genhtml /home/administrator/coverage1.dat /home/administrator/coverage2.dat
I got the following output and problem:
Reading data file /home/administrator/coverage1.dat
Reading data file /home/administrator/coverage2.dat
genhtml: Can't use an undefined value as a HASH reference at genhtml line 1506.
And it failed to generate anything.
I played around with the files, and discovered that one reason might be because of the repeating headers and files in the coverage data.
Is this a known issue, or does anyone know a way to get around it, or am I on the wrong track?
Thanks.

我已经从sourceforge下载了最新的lcov和genhtml。它解决了问题。
谢谢。
I have downloaded the latest lcov and genhtml from sourceforge. It fixed the problem.
Thanks.
该消息是由于尝试取消引用未定义的值（就好像它是哈希引用一样）而导致的致命错误。
genhtml 中存在错误或您的数据文件已损坏。
您是否尝试过在 lcov 邮件列表上询问？
The message is a fatal error caused by trying to dereference an undefined value as if it were a hash reference.
There is either a bug in genhtml or your data files are corrupt.
Have you tried asking on the lcov mailing list?
