insight & ddd

[Ian Gilmour]

I've used ddd for a while and am just starting off using insight.
I've got a gdb user macro in ~/.gdbinit that runs fine using
powerpc-eabi-gdb (insight version) but when I run the same 
macro using ddd as the front-end (and insight as the gdb backend) I get...

load
rbreak cyg_user_start
rbreak cyg_test_exit
rbreak cyg_assert_fail
end
------------------------------
Any clues as to whether this is a ddd problem, an insight problem or my
config?
Do I need a raw version of gdb to overcome it?
Any ideas?
N.B. Host is linux.

cheers,

Ian

Insight, like DDD, is just a GUI on top of GDB. If you're seeing a crash 
in the command line, you'll need to ask over on gdb@sources.redhat.com.

You'll need a backtrace to know for sure where things are going astray, 
but I would recommend narrowing the testcase down a little. It looks like 
"rbreak" is the culprit. Does command-line GDB behave the same way? 
(That's the Insight version of GDB with the "-nw" flag.) The gdb folks 
will want to know. (Also include info from 'gdb -v'.)
