Package: xterm
Version: 244-1
Severity: normal

Hi,

I just noticed that xterm doesn't like it very much to be resized: when I grab
a window edge and make a circular motion (i.e. enlarge and shrink again in
both dimensions), I usually get it to segfault within fractions of a second.
Here are a few backtrace samples...

Description: 
 xterm      - X terminal emulator
Closes: 531597 541089 541160 541236 541603
Changes: 
 xterm (246-1) unstable; urgency=low
 .
   * New upstream release
     + interaction between allowSendEvents and the various allowXXXOps
       resources clarified in manpage (closes: #531597)
     + remove obsolete logic for saving/restoring wrapping flags, which did not
       work on 64-bit platform.  Wrapping flags (stored in the line-index) are
       now copied with line-data (closes: #541160)
     + modify comments in app-defaults files to avoid problem with C
       preprocessor used by xrdb (closes: #541603)
     + restore special case in makeColorPair needed for colorBDMode resource
       (closes: #541089)
     + correct SetLineFlags() macro, broken in patch #244 when recoding to
       avoid gcc-specific bitfields (closes: #541236)
   * The issues with the fifo-lines code should now be fixed, so enable it
     again.
