Package: gdb Version: 7.6.1-1 Severity: important X-Debbugs-CC: debian-s390@lists.debian.org Dear Maintainer, gdb seems to be completely useless on s390x. I tried running it against various executables (both buggy and sane). gdb seems to launch the executable, however the subprocess doesn't seem to be doing anything. gdb just gives a message, but it does not even seem to consider the situation fatal and just seats there, apparently considering that the subprocess is running faultlessly. Example session on "echo foo", notice how "foo" is not echoed: ________________ GDB SESSION _______________________ (sid_s390x-dchroot)thibaut@zelenka:~$ gdb --args echo foo GNU gdb (GDB) 7.6.1 (Debian 7.6.1-1) Copyright (C) 2013 Free Software Foundation, Inc.
