Description Karsten Keil 2005-09-23 15:42:11 UTC 
While debugging a X11 program I want to do single stepping on the top level 
of the program. But if it is loading libs via dlopen, it always stops on 
_dl_catch_error. I did not enable anz special catch points.
Comment 1 Andreas Schwab 2005-10-21 14:41:13 UTC 
Single stepping always steps until a different source line is reached.
Comment 2 Karsten Keil 2005-10-24 16:39:15 UTC 
But next should stop on the next program line in the same source and should not doing signle stepping into the function call.
Comment 3 Andreas Schwab 2005-11-07 15:22:05 UTC 
Please provide a fully-contained test case.

you do not need any isdn equipment for this testcase, but you need to load the module isdn (modprobe isdn).
Then do following to see the issue:
cd isdn4k-utils/xisdnload
gdb ./xisdnload
break 519
run
n
n
and you are not on the next line, but in _dl_catch_error()

Works fine here.
Comment 6 Karsten Keil 2005-11-11 18:11:22 UTC

I'm using 10.0 final and no extra gdb init file.
