Hi,
Would you mind filing a bug on http://sourceforge.net/projects/ddd/ ?
Patch are welcome.

Subject: DDD Set Value doesn't work
Hello,
When I try to set a value into register using the Set button, the following
error is reported,
"A parse error in expression, near `/x $g5 = 0x100'"
When I try to set a value into a memory location using Set button, the
following error is reported,
"Invalid character '`' in expression"
I am using ddd-3.3, gdb-6.0, gcc-2.95.3. I just tried with simple "Hello
world" C program.
Can anyone please advice me, what's wrong and how to fix this ?
I have attached the ~/.ddd/log file.
Thanks,
Iyappan
