            Bug ID: 29244
           Summary: [gdb/testsuite, gcc 4.8] Problems with -static and
                    target board unix/-fPIE/-pie
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: testsuite
          Assignee: unassigned at sourceware dot org
          Reporter: vries at gcc dot gnu.org
  Target Milestone: ---

On openSUSE Leap 42.3 and gcc 4.8.5, and target board unix/-fPIE/-pie I'm
running into a cluster of FAILs:
...
FAIL: gdb.arch/amd64-disp-step-avx.exp: running to main in runto
FAIL: gdb.arch/amd64-init-x87-values.exp: check_setting_mxcsr_before_enable:
running to main in runto
FAIL: gdb.arch/amd64-init-x87-values.exp: check_setting_x87_regs_before_enable:
running to main in runto
FAIL: gdb.arch/amd64-init-x87-values.exp: check_x87_regs_around_init: running
to main in runto
FAIL: gdb.dwarf2/frame-inlined-in-outer-frame.exp: frame
FAIL: gdb.dwarf2/frame-inlined-in-outer-frame.exp: starti prompt
FAIL: gdb.dwarf2/frame-inlined-in-outer-frame.exp: step back into _start (the
program is no longer running)
FAIL: gdb.dwarf2/frame-inlined-in-outer-frame.exp: step back into foo (the
program is no longer running)
FAIL: gdb.dwarf2/frame-inlined-in-outer-frame.exp: step into bar (the program
is no longer running)
FAIL: gdb.dwarf2/frame-inlined-in-outer-frame.exp: step into foo (the program
is no longer running)
...

The problem is that the compilation fails to produces an usable static
executable, instead we get a shared library, and we trying to execute it we run
into "No such file or directory".

More specifically:
...
(gdb) run ^M
Starting program: /data/vries/gdb_versions/devel/build/gdb/testsuite/outputs/g\
db.arch/amd64-disp-step-avx/amd64-disp-step-avx ^M
/bin/bash: /data/vries/gdb_versions/devel/build/gdb/testsuite/outputs/gdb.arch\
/amd64-disp-step-avx/amd64-disp-step-avx: No such file or directory^M
During startup program exited with code 127.^M
(gdb) FAIL: gdb.arch/amd64-disp-step-avx.exp: runto: run to main
...
and:
...
$ file
/data/vries/gdb_versions/devel/build/gdb/testsuite/outputs/gdb.arch/amd64-disp-step-avx/amd64-disp-step-avx 
/data/vries/gdb_versions/devel/build/gdb/testsuite/outputs/gdb.arch/amd64-disp-step-avx/amd64-disp-step-avx:

...

Possibly the error message corresponds to the missing interpreter:
...
$ readelf -p .interp
/data/vries/gdb_versions/devel/build/gdb/testsuite/outputs/gdb.arch/amd64-disp-step-avx/amd64-disp-step-avx 

String dump of section '.interp':

$ ls -al /lib/ld64.so.1

...
