[R段错误读取XML

时，我有以下XML文件[R段错误读取XML

<conf> 
<Constraints> 
<BETA>0</BETA> 
</Constraints> 
</conf>

当我尝试加载这个XML

R> library(XML) 
R> xmlParse('test.xml') 

*** caught segfault *** 
address 0x3a00000000, cause 'memory not mapped' 

Traceback:

有什么我需要在R装入一个XML文件之前评估？

的XML文件（根据网页XML验证）似乎为语法正确

我创建了一个新的文件，并粘贴以上几行代码，并坠毁都是一样的，所以它不会出现在文件格式...

R> sessionInfo() 
R version 3.3.0 (2016-05-03) 
Platform: x86_64-redhat-linux-gnu (64-bit) 
Running under: CentOS release 6.6 (Final) 

locale: 
[1] C

我试着xml2

R> library(xml2) 
R> read_xml(
x=   encoding= ...=  as_html= options= n=   verbose= base_url= 
R> read_xml(x = 'test.xml') 

*** caught segfault *** 
address 0x3a00000000, cause 'memory not mapped' 

Traceback: 
1: .Call("xml2_doc_parse_file", PACKAGE = "xml2", path, encoding,  as_html, options) 
2: doc_parse_file(con, encoding = encoding, as_html = as_html, options = options) 
3: read_xml.character(x = "test.xml") 
4: read_xml(x = "test.xml")

我的想法是，通过这些包所用的libXml2库必须这里有毛病......虽然我不知道如何测试这个

g++ -m64 -I/usr/include/R -DNDEBUG -I/usr/include/libxml2 -I/usr/local/include -I"/pxfs1/home/user/R/x86_64-redhat-linux-gnu-library/3.3/Rcpp/include" -I"/pxfs1/home/user/R/x86_64-redhat-linux-gnu-library/3.3/BH/include" -fpic -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64 -mtune=generic -c RcppExports.cpp -o RcppExports.o

的libxml2的我已经是相当落伍：

$ rpm -qa |grep -i libxml2 
libxml2-2.7.6-17.el6_6.1.i686 
libxml2-python-2.7.6-17.el6_6.1.x86_64 
libxml2-devel-2.7.6-17.el6_6.1.i686 
libxml2-2.7.6-17.el6_6.1.x86_64 
libxml2-devel-2.7.6-17.el6_6.1.x86_64

是的编译XML包的后端？你的xml文件有多大？我首先想到的问题是使用另一个XML库。 – snaut

对不起，我错过了你也发布了整个xml文件。 segfault是编译函数失败的提示。两个失败的函数都会在内部调用编译函数。确保你所有的软件包都是最新的版本和适合你的R安装的版本。请张贴包和R版本。 – snaut

对不起，很显然我今天不是很集中，我希望其他人更有帮助。 – snaut

更新libxml2工作
