Stefan Liebler 28669f86f6 Fix segfault in maybe_script_execute. ... If glibc is built with gcc 8 and -march=z900, the testcase posix/tst-spawn4-compat crashes with a segfault. In function maybe_script_execute, the new_argv array is dynamically initialized on stack with (argc + 1) elements. The function wants to add _PATH_BSHELL as the first argument and writes out of bounds of new_argv. There is an off-by-one because maybe_script_execute fails to count the terminating NULL when sizing new_argv. ChangeLog: * sysdeps/unix/sysv/linux/spawni.c (maybe_script_execute): Increment size of new_argv by one.		2018-09-06 14:27:03 +02:00
