Package: gdb
Version: 8.3-1
Severity: important
Dear Maintainer,
When gdb is asked to start any dynamically-linked program, they segfault,
seemingly early on launch:
$ echo 'int main(void) { return 0; }' | gcc -o /tmp/prog -x c - && gdb -q
/tmp/prog
Reading symbols from /tmp/prog...
(No debugging symbols found in /tmp/prog)
(gdb) run
Starting program: /tmp/prog
Program received signal SIGSEGV, Segmentation fault.
0x0000000000000000 in ?? ()
(gdb) bt
#0 0x0000000000000000 in ?? ()
#1 0x000055555555506a in _start ()
Pre-built programs like /bin/true also segfault, but the problem doesn’t seem
to affect statically-linked programs:
$ echo 'int main(void) { return 0; }' | gcc -static -o /tmp/prog -x c - && gdb
-q /tmp/prog
Reading symbols from /tmp/prog...
(No debugging symbols found in /tmp/prog)
(gdb) run
Starting program: /tmp/prog
[Inferior 1 (process 1279) exited normally]
