.Internal(La_rs(x,FALSE))仅在Windows上经过长(可重现)脚本后崩溃

Question

在.Internal(La_rs(x,FALSE))该内部通话eigen中使用的功能fields:::Krig.engine.default会导致我的[R控制台[1]它被一个巨大的脚本中触发后崩溃.

我确信那是导致引爆的线.但是,同一行不会在使用以下内容的新会话中崩溃:

x <- structure(c(0.00251355321405019, -0.000589785531216647, -0.000172411748626129, -0.000589785531217227, 0.000897505637785858, -0.000714600035538855, -0.000172411748626269, -0.000714600035538766, 0.00123946691634644), .Dim = c(3L, 3L))
.Internal(La_rs(x,FALSE))

您可以使用以下三行重现此控制台崩溃(大约需要十分钟):

# install.packages( c("MonetDB.R", "MonetDBLite" , "survey" , "SAScii" , "descr" , "downloader" , "digest" , "sas7bdat" , "R.utils" ,"survey","ggplot2","scales","mapproj","sqldf","maptools","raster","rgeos","stringr","plyr","mgcv","spatstat","rgeos") , repos=c("http://dev.monetdb.org/Assets/R/", "http://cran.rstudio.com/"))
# path.to.7z <- "7za"       # macintosh/unix users need to specify 7z
#  setwd("C:/My Directory/")

对不起这个例子不是更小,当我删除不同的东西时崩溃消失了..

2016年2月22日编辑:更糟糕的是,当我尝试一个旨在自行触发崩溃的脚本时,它不会死!

谢谢!

[1] R版本3.2.3(2015-12-10)平台:x86_64-w64-mingw32/x64(64位)

如果我立即运行整个脚本,R在Rterm.exe中没有任何信息崩溃.但如果我将脚本分成两部分,R会给我这个错误:

多一点调试信息:看起来.Internal()函数La_rs已被破坏了吗？

2016年2月21日更新:我能够在第二个Windows脚本上重现此错误(没有R dying).这是永久链接

这是在错误点发生的事情.再次La_rs出现腐败.

Answer 1

哇，这个错误很难重现。重现所需的步骤数量可能是您没有得到很多答案的原因。

我终于设法将所有数据下载并安装到重现中，但还没有让您的代码（相当复杂）达到您指示它尚未失败的程度。

根据我所做的评论，错误消息表明正在lapack尝试执行您正在使用的函数的复杂版本（此行引发错误），但输入变量的类型不是矩阵，因此它会触发错误。这很可能是低级根本原因。

不过，您可能真正想要答案的问题是为什么会发生这种情况？

我怀疑这意味着您的步骤之一的输入数据要么是空的，要么是一维的。我将继续尝试重现来证明这个理论。
