Package: ddd
Version: 1:3.3.11-1ubuntu2
Severity: normal
Tags: patch
Using ddd with gdb, Machine Code Window (View -> Machine Code Window) does not
show disassembled code; instead, you can see the message "A syntax error in
expression, near `<hex_address>'.
The bug is caused by ddd using the old syntax for gdb command "disassemble",
which used to require blank space as a separator between starting and ending
address. The new syntax (introduced by a commit from Paul Pluzhnikov on
november 23rd, 2009) requires a comma between the two addresses.
This happens on Ubuntu Lucid, with ddd version 1:3.3.11-1ubuntu2 and gdb
version 7.1-1ubuntu2, but Debian package ddd 1:3.3.12-2 still presents the
issue.
This trivial patch, along with a change in gdb dependency version, restores the
correct behaviour:
