Dear all,?
I am not sure if this is a bug, so I prefer to post it here before filing.
After upgrading to 3.4 I encounter the following message with mclapply:
Assertion failure at kmp_runtime.cpp(6480): __kmp_thread_pool == __null.OMP: Error #13: Assertion failure at kmp_runtime.cpp(6480).OMP: Hint: Please submit a bug report with this message, compile and run commands used, and machine configuration info including native compiler and operating system versions. Faster response will be obtained by including all program sources. For information on submitting this issue, please see?http://www.intel.com/software/products/support/.
The complete pdf of what console produces is here:https://www.dropbox.com/s/navugg28gqne14p/R%20Console.pdf?dl=0
The batch with commands to (hopefully) reproduce it is here:https://www.dropbox.com/s/8pd0ij3kowigdlc/20170430%20-%20R%20mclapply%20bug%20report.r?dl=0
The data for the reproducible example is here:

Note that this behavior was not present in R 3.3.3 on the same machine and all the batch was working without any errors.
