I have to add from RH5.2 thru RH7.2 tkdesk always opened flawlessly.
It is only now with RH7.3 that I have the problem to which I have (foolishly)
upgraded a few days ago.
Ray, my guess is that is has something to do with the new libraries. How would
I find out which one. ldd tkdesk gives "not a dynamic executable".
I still have RH6.2 running and could transfer the libraries from there.
From the ldd response, I'd infer that it is a script rather than an executable, presumably an tcl script from the beginning of its name. You might want to ldd tcl (or whatever the right name is -- see what interpreter the tkdesk script is invoking on its shebang line). But Tcl itself *seems* (I'm not certain because I do not have it installed) to depend only on libc6, and I'd be surprised if RH's install of libc6 is buggy (or its bugs would show up everywhere, this lib being so central to all apps).
You might also want to make sure that even after you install TCL 8.0, tkdesk uses it rather then the more recent version of Tcl that RH has installed.
As to the strace output you included, I can pretty much read it, but I don't see where or why it is segfaulting. Perhaps whoever suggested using strace will be better able to spot the exact problem than I am. The last statement executed -- the munmap -- appears correctly to be releasing the 4096 bytes of memory that were allocated by mmap a few lines earlier, and the several reads right before it look OK too. So I'm missing it, whatever it is. Sorry.
If I try to re-./.configure I get error:
checking version of Tcl/Tk... 8.3/8.3
TkDesk requires Tcl/Tk versions 7.5/4.1, 7.6/4.2., or 8.0.
Older versions are unlikely to work, while newer ones are not
yet supported
So I copied Tcl/Tk...8.0 from RH6.2 over to RH7.3 and I still get the same
error.

There is no core file created.
