Bug#1125796: all(?) programs segfault running under gdb

Package: gdb
Version: 17.1-1
Severity: grave
X-Debbugs-Cc: [email protected]
User: [email protected]
Usertags: armhf

On amdahl,

$ cat <<EOF > hello.c
#include <stdio.h>
int main(int argc, char **argv){
    printf("hello world\n");
}
EOF

$ gdb ./a.out
Reading symbols from ./a.out...
(No debugging symbols found in ./a.out)
(gdb) run
Starting program: /home/bremner/notmuch-0.39/a.out

Program received signal SIGSEGV, Segmentation fault.
0xf7fc682a in ?? () from /lib/ld-linux-armhf.so.3
(gdb) 

I tried 4 executables: /usr/bin/ls, notmuch (compiled from 0.39 and
0.40~rc1 source, and hello world). It seems to me that gdb us
currently unusable on armhf, hence the severity. As always feel free
to choose a more appropriate severity if I missed something.
