Hi,<br>
<p>
In a message titled "segfault with sane-umax", Iain O'Cain<br>
&lt;<a href="mailto:ec@intranet.org">ec@intranet.org</a>&gt; described his problems with scanimage crashing<br>
with segfaults. I have the same problems (I wont repeat the<br>
detailed description, since the symptoms are exactly as describe<br>
there)<br>
<p>
I use a umax ASTRA 1200S scanner, which works fine with the<br>
standalone "umax-cli" program by Michael K. Johnson<br>
&lt;<a href="mailto:johnsonm@redhat.com">johnsonm@redhat.com</a>&gt; and Oliver Rauch<br>
&lt;<a href="mailto:Oliver.Rauch@Wolfsburg.DE">Oliver.Rauch@Wolfsburg.DE</a>&gt;.<br>
<p>
I tried to locate the error- it seems like the crash occurs not<br>
in scanimage itself, but in the c library when the program exits.<br>
It looks like free is being called with an invalid address. The<br>
crash occurs with libc 5.4.33 as well as 5.4.38. With an ancient<br>
library version (5.0.9) scanimage and xscanimage work.<br>
<p>
Maybe somebody can make any sense of this and figure out what's<br>
going wrong...<br>
<p>
cheers,<br>
Peter<br>
