Description John Klingler 2001-01-04 19:57:35 UTC

Using ddd-3.2-4 to edit gdb settings causes gdb-5.0-7 to get
a segmentation fault.

Here's the stack:

Segmentation fault

Comment 1 Trond Eivind Glomsrxd 2001-01-05 12:29:50 UTC

Please try 5.0-11 in Rawhide.

Comment 2 Trond Eivind Glomsrxd 2001-01-20 23:29:34 UTC

Have you tried the Rawhide version yet? Also, exactly how did you produce this bug?

Comment 3 John Klingler 2001-01-23 20:15:27 UTC

I upgraded to gdb-5.0-11 and it still happens but is not predictable. 
I was debugging an OpenMotif application and trying to print out a
struct. I was able to use printf's to get around this. I will try to
contruct a small program to isolate the problem. (Sorry, I should have
done this the first time.)

Comment 4 Trond Eivind Glomsrxd 2001-03-01 19:42:48 UTC

I can still reproduce this (message of gdb segaulting) just by choosing "edit gb
preferences." Debugging this is a pain.

Comment 5 Trond Eivind Glomsrxd 2001-05-16 15:23:30 UTC

Fixed in gdb-5.0rh-9 - coming soon to Rawhide, available for a limited time from
