I'm using R scripts with C++ code under the hood. An error message references a Jenkins Workspace with the file I'd like to debug. The workspace directory appears to be temporary and I'm unable to find this file:

c:\jenkins\workspace\mxnet\mxnet\src\operator\tensor../elemwise_op_common.h:123: Check failed: assign(&dattr, (*vec)[i])

How should the directory c:\jenkins\workspace\... be understood?

Where would I look for the header file elemwise_op_common.h?
