Bison内存损坏

Question

我试图从git源代码中编译星号开放源码PBX，在运行./configure之后，我在检查野牛对解析的支持时几乎立即遇到了一个不寻常的错误--它碰到了一种分段错误，或者更确切地说，是内存损坏，通过挂在捕获的内存损坏处，使进程完全停止。

checking for bison that supports parse-param... *** Error in `/usr/bin/bison': double free or corruption (!prev): 0x00000000011d8760 ***
*** Error in `/usr/bin/bison': malloc(): memory corruption: 0x00007f4c5affd010 ***

我不太清楚是什么原因造成的，也不知道为什么会发生这个错误。我已经安装了编译星号所需的所有东西。

如果它有帮助的话，我会跟踪这个命令，这是它输出给野牛的；

查看星号源，它看起来实际上并不需要Bison来编译。它通常会使用已经生成的C文件。如果崩溃阻止配置脚本运行到完成，那么使用./configure BISON=/bin/true运行它，这应该会让它完成。

或者，您可以下载最后一个GNU源代码，编译，安装它，然后使用BISON=/path/to/bison将星号配置脚本指向它。我建议您在发行版使用的任何版本的bison++上使用常规的GNU源代码。GNU版本可能没有相同的bug，而且更有可能具有配置脚本正在测试的“解析-param”特性。

这个bug似乎已经在Ubuntu跟踪器：https://bugs.launchpad.net/ubuntu/+source/bison++/+bug/80975中报告过了。
