[karan-kang]

Version

npm: 3.10.10
cross-var: 1.0.3
OS: Win 10

Steps

• Create a npm command which will output lot of logs file, like a highly verbose webpack build
• Use cross-var to run this command
• The following error will be thrown, and no output will be generated while the command is being executed.

exec error: Error: stderr maxBuffer exceeded

Expected cross-var should pipe the output to console to prevent buffer from exceeding.
