Insight debug window crashes

Insight debug window crashes

[Martin M. Hunt]

Anyone else see this with a recent build?

export GDBTK_DEBUG=2
./gdb gdb
debug window comes up then source window, then X-server crashes.

On RedHat 7.1 and 7.1 I am gettin X-server crashes when the debug window is 
opened before the source window while debugging gdb with itself  I have 
traced this down to srcwin.itb in the following method:

body SrcWin::fillNameCB {} {
  global _files
  set allfiles [gdb_listfiles]
  debug "gdb_listfiles returned $allfiles"

When debugging GDB with itself, $allfiles is almost 10,000 characters.  There 
appears to be some problems when writing this to the text window that causes 
my X-server to crash.  Not all X-servers crash; for example Xnest works fine 
for me.

It seems to me this is most likely a tk bug that generates a bad X command 
that crashes some X-servers.  I think tk bug instead of X bug because this 
does not happen with the old tcl/tk.

Any suggestions for a fix?  We could truncate debug output to something 
reasonable or have the debug code break long output up into smaller lines.  
Or someone with a lot of time could take a look at tk.

Well, as we've discussed, I don't see this problem on linux (RH7.0,
XFree86 4.0.1).

I tried my new P4 box, too. Also had no problems with XFree86-4.0.3 (it's
running RH7.1).

Anyone seeing problems at all under X?

I tried my little torture test (stepi 5000 times with all windows open),
and it passed without problems. (Although the string_to_core_addr did call
internal error when the memory window is opened with no inferior. The pc
is "No registers.")
