Since [commit] [testsuite patch] Fix gcc_compiled for gcc 6 & 7 https://sourceware.org/ml/gdb-patches/2016-10/msg00620.html there has started running again Running gdb/testsuite/gdb.base/morestack.exp ... +FAIL: gdb.base/morestack.exp: continue +PASS: gdb.base/morestack.exp: up 3000 but as you can see it FAILs now - on Fedora 24 x86_64 (although for example it still PASSes on CentOS-7.2 x86_64). Program received signal SIGSEGV, Segmentation fault. 0x00007ffff787c7bb in malloc_consolidate (av=av@entry=0x7ffff7bbcb00 <main_arena>) at malloc.c:4181 4181 unlink(av, nextchunk, bck, fwd); (gdb) bt [...] [...] This apparently is due to - man gcc - -fsplit-stack: When code compiled with -fsplit-stack calls code compiled without -fsplit-stack, there may not be much stack space available for the latter code to run. If compiling all code, including library code, with -fsplit-stack is not an option, then the linker can fix up these calls so that the code compiled without -fsplit-stack always has a large stack. Support for this is implemented in the gold linker in GNU binutils release 2.21 and later. gdb/testsuite/ChangeLog 2016-10-24 Jan Kratochvil <jan.kratochvil@redhat.com> * gdb.base/morestack.exp: Try to build it using -fuse-ld=gold first. |

README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
