Crashed when using strace on Spotify Linux Client.

Was trying to find which shared libraries are needed for playing local files.

Status changed to 'Confirmed' because the bug affects multiple users.

Probably Spotify Linux Client process did crash with SIGABRT. strace detects that child was killed with the signal and raises same signal for itself just before exit (like in Bug #1062412)

There is a code in strace.c (main -> terminate() ) to raise the signal which killed the traced process. Strace does it exactly before exit
https://github.com/strace/strace/blob/1d98b287a4cb6901d369d78126d481508f9e35ef/strace.c#L2655

 if (exit_code > 0xff) {
  ...
  /* Child was killed by a signal, mimic that. */
  exit_code &= 0xff;
  signal(exit_code, SIG_DFL);
  ...
  raise(exit_code);
 ...
 exit(exit_code);

Code was added in 2008-09-29 commit
