This patch unbreaks ghci on GRSEC kernels hardened with TPE (Trusted Path Execution) protection. TPE forbids mmap('rwx') files opened for writes: fd = open (a_file_in_tmp, O_RDWR); mmap (..., PROT_READ | PROT_WRITE | PROT_EXEC, fd); while allows anonymous RWX mappings: mmap (...MAP_ANONYMOUS , PROT_READ | PROT_WRITE | PROT_EXEC, -1); Thanks to klondike for finding it out. The result of a horrible typo. (unreleased yet) upstream also has the patch: http://github.com/atgreen/libffi/commit/eaf444eabc4c78703c0f98ac0197b1619c1b1bef
