Bug#739613: flac encode crashes if called as a python subprocess

[Cedric Andrieu]

Package: flac
Version: 1.3.0-2
Severity: normal

Dear Maintainer,

The jack CD ripper package in debian fails when calling the flac
encoder. This is logged in bug #720782.  This happens since the flac
package upgrade to upstream 1.3.0.x
Look at https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=720782

After some digging, I believe the bug shall be corrected inside flac
which does a divide by zero when not called from a terminal.

file: src/flac/utils.c

function: get_console_width(void)

{
	int width = 80;
#if defined _WIN32
	width = win_get_console_width();
#elif defined __EMX__
	int s[2];
	_scrsize (s);
	width = s[0];
#elif !defined __ANDROID__
	struct winsize w;
	if (ioctl(STDOUT_FILENO, TIOCGWINSZ, &w) != -1)	width = w.ws_col;
#endif
	return width;
}


shoudl be
int get_console_width(void)
{
	int width = 80;
[...]
#elif !defined __ANDROID__
	struct winsize w;
	if (ioctl(STDOUT_FILENO, TIOCGWINSZ, &w) == -1 || w.ws_col == 0 )
    width = 80;
  else
		width = w.ws_col;
#endif
	return width;
}

this way we always have a default at 80 chars.

Hope this helps,

Ced
