Subject: Segmentation fault in static binaries built with recent binutils


Debian recently updated binutils from 2.30 to 2.31.
When compiling simple static binaries with musl (1.19 and git)
they segfault on startup (dynamic linking still works fine).
With the previous binutils version it is running successfully.

  $ cat test.c 
  int main() { return 0; }
  $ musl-gcc -ggdb3 -O0 -static test.c
  $ gdb ./a.out 
  GNU gdb (Debian 8.1-3) 8.1
  Reading symbols from ./a.out...done.
  (gdb) run
  Starting program: /tmp/test/a.out 
  Program received signal SIGSEGV, Segmentation fault.
  0x000000000040159d in static_init_tls ()
  (gdb) bt
  #0  0x000000000040159d in static_init_tls ()
  #1  0x0000000000000000 in ?? ()

Is this a bug in musl or should I report it to binutils?

Kind regards,
