# Flang对多维数组的大小支持有限

对于多维数组，当每一维的元素个数比较多，生成的IR大于2GB时，会编译失败。失败信息如下：

```
clang::FileID clang::SourceManager::createFileID(const clang::SrcMgr::ContentCache*, llvm::StringRef, clang::SourceLocation, clang::SrcMgr::CharacteristicKind, int, unsigned int): Assertion `NextLocalOffset + FileSize + 1 > NextLocalOffset && NextLocalOffset + FileSize + 1 <= CurrentLoadedOffset && "Ran out of source locations!"' failed.
```

或如下：

```
fatal error: sorry, this include generates a translation unit too large for Clang to process.
```
