Hi Evgeniy, This fix causes me trouble in the emulator because of the execv(argv[0]): http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20140217/205359.html Instead using setrlimit from within the C++ code, can you set the stack limit using ulimit on the RUN lines? Also, should this test be moved to the Posix or Linux directory? Thanks, Greg
