当我在Perl中打印到stderr时，为什么IIS崩溃? [英] Why does IIS crash when I print to stderr in Perl?

问题描述

这让我发疯了.我们有IIS(6)，Windows 2008和ActiveState Perl 5.10.由于某种原因，无论何时我们发出警告或鲤鱼，它最终都会破坏应用程序池.当然，这很重要，因为这意味着我们的错误实际上会引起问题.

This has been driving me crazy. We have IIS (6) and windows 2008 and ActiveState Perl 5.10. For some reason whenever we do a warn or a carp it eventually corrupts the app pool. Of course, that's a pretty big deal since it means that our errors actually cause problems.

这是在Perl(5.8)和Windows(2003)和IIS(5)的早期版本中发生的.无论如何，基本上，我放入carp或warn并得到一条错误消息，然后出现一些垃圾文本.有什么想法吗?

This happened with the previous version of Perl (5.8) and Windows (2003) and IIS (5.) Anyway, basically I put in a carp or a warn and I get an error message and then some garbage text. Any thoughts?

推荐答案

检查以确保IIS和perl DLL与相同版本的C运行时库链接. (使用depends.exe或dumpbin/depends).

Check to make sure that IIS and the perl DLL are linked with the same version of the C runtime library. (Use depends.exe or dumpbin /dependents).

展开:问题可能是IIS将其FILE *表放在一个位置，而perl DLL认为它将在稍有不同的位置.当perl找到stderr句柄时，它将随机内存视为文件句柄，结果可预测.

To expand: the problem may be that IIS has its FILE* table in one place, and the perl DLL thinks it's going to be in a slightly different place. When perl goes to find the stderr handle, it treats random memory as a file handle, with predictable results.
