I think the problem is in ddd since gdb (which I'm clumsy at using) seems quite stable. ddd frequently crashes. I'm sorry that I don't have anything more useful to point at, but I'm willing to supply more detail if I know what would be useful. Probably not relevant, but when ddd starts it puts up an error window saying "/var/tmp/portage/glibc-2.3.4.20050125-41/work/build-default-x86_64-pc-linux-gnu-linuxthreads/csu/crti.S:No such file or directory" This is version 3.3.10 of DDD, compiled with gcc 3.4.3-20050110. I'd be happy to help if I have some idea of what would be useful. I should note that I'm using masked versions of gcc and glibc. With the unmasked versions things are much worse.

Forgot to mention that when running ddd my hardware monitor is showing a lot of network traffic, which ends as soon as ddd is killed (after dying).
Scratch that comment about the network. The order of things in the hardware monitor and gotten exchanged. Sorry.
I am having similar problems but on x86. Has there been a fix for this yet?
Nohting new on this. I might mention that ddd tends to crash when moving the mouse cursor in the source window. I'm not sure that it ever crashes when moved in debugger console or data windows. Also I think I've only had the problem with Fortran source. (I am not currently doing much in C.)
Just to keep this a little more up to date. I'm now on version 3.3.11 of ddd, glibc-2.3.5-r3,and gcc-3.4.4-r1. The error message when starting now says /var/tmp/portage/glibc-2.2.5-r3/work/build-amd64-x86_64-pc-linux-gnu-linuxthreads/csu/crti.S: No such file or directory. It would seem that fixing this diagnostic or giving instructions on how to avoid it should not be a big deal for someone who understands how this all works. (I do realize that such might be a rare beast.) Perhaps with this fixed the other problem would go away. I'm wondering if something like the patch at http://forums.gentoo.org/viewtopic-t-376943.html is something that might be needed. (I'm not going to much with glibc unless I've got a very good reason.)
The problem appears to be fixed on my machine. I had use flags for motif and lesstif. I removed lesstif from my use flags and re-emerged ddd. It no longer seems to crash when moving the cursor in the source window of Fortran codes. Perhaps motif should be required with ddd?
*** Bug 116886 has been marked as a duplicate of this bug. ***
Reopen.
I don't know why it has taken me so long to notice this, but it appears that what makes the code crash is to move the cursor in the source window over a dummy array. Other dummy arguments cause no problem. Perhaps this will suggest where the problem is? Many thanks.
I have posted this to the ddd bugs on the ddd home site with full details, but it may be of interest here. Below is a very short Fortran code. If you run it in ddd, set a break on the next to last line, then move the mouse cursor over the array II then ddd will crash every time. (Or at least it does for me.) c Program to show problem in ddd integer I, IA(5) call sub1(IA) print *, (IA(I), I = 1, 5) stop end subroutine sub1(II) integer I, II(*) do 10 I = 1, 5 II(I) = I 10 continue return end
Sorry, I should have mentined this awhile back. This problem is gone when using the new Fortran compiler. I'm now using GNU Fortran 95 (GCC) 4.1.1 (Gentoo 4.1.1-r1). I've changed the status to FIXED although I'm not sure that is the right term. There is no choice for "No longer relevent".
