<TITLE>rxfax as of 03-16, crash in libtiff-3.5.7-11</TITLE>
</HEAD>
<BODY>
<P><FONT SIZE=2>Hi,</FONT>
</P>
<P><FONT SIZE=2>RH9 (2.4.22 #4 SMP)</FONT>
</P>
<P><FONT SIZE=2>The 10-21-2003 release of softfax had it's problems but didn't crash in libtiff-3.5.7-11.</FONT>
<BR><FONT SIZE=2>The 03-16-2004 release does.</FONT>
</P>
<P><FONT SIZE=2>Questions:</FONT>
<BR><FONT SIZE=2>1. Does it make sense to upgrade to libtiff-3.6.0?</FONT>
<BR><FONT SIZE=2>2. We don't use the latest source in our asterisk build, can it break app_rxfax?</FONT>
<BR><FONT SIZE=2>3. Any help is appreciated.</FONT>
