Re: segfault with sane-umax

Hi,

In a message titled "segfault with sane-umax", Iain O'Cain
<ec@intranet.org> described his problems with scanimage crashing
with segfaults. I have the same problems (I wont repeat the
detailed description, since the symptoms are exactly as describe
there)

I use a umax ASTRA 1200S scanner, which works fine with the
standalone "umax-cli" program by Michael K. Johnson
<johnsonm@redhat.com> and Oliver Rauch
<Oliver.Rauch@Wolfsburg.DE>.

I tried to locate the error- it seems like the crash occurs not
in scanimage itself, but in the c library when the program exits.
It looks like free is being called with an invalid address. The
crash occurs with libc 5.4.33 as well as 5.4.38. With an ancient
library version (5.0.9) scanimage and xscanimage work.

Maybe somebody can make any sense of this and figure out what's
going wrong...

cheers,
Peter
