Public bug reported:
Binary package hint: gcc
cdebootstrap on x86_64 hangs whenever it tries to fork/exec a child
process. It appears that this is miscompiled:
if (pid <= 0)
{
close (fds_status[0]);
close (fds_stdout[0]);
close (fds_stderr[0]);
}
if (pid == 0)
internal_di_exec_child (filename, argv, envp, pid, child_prepare_handler,
child_prepare_user_data, fds_status[1], fd_null, fds_stdout[1], fds_stderr[1]);
close (fd_null);
strace shows that the child process gets to the close(fd_null) without
executing any of the statements inside internal_di_exec_child().
The later function is marked attribute((noreturn)). If I remove that
attribute, then things work properly.
** Affects: gcc-defaults (Ubuntu)
Importance: Undecided
Status: New
