GDB Problems
I have recently been expriencing problems with GDB. I will compiling a program with the -g symbol and run it in gdb. After setting a break point(typically line one worked in the past) and running the program I get this: Cannot insert breakpoint 1: Cannot access memory at address: some memory address I have been getting this error since I reinstalled linux. Is this a bad setting I've encountered or something else? Perhaps I've overlooked something. Any help in fixing this would be appreciated.

Glad to know it isn't me losing my mind, but a solution would be wonderful. I have yet to find one :( SJG

Hi Debian users,

gdb problems
Hi, my gdb seems to be having problems lately. I need to make SIGSEGV a "nostop" and "noprint" for gdb, but it's refusing to do it, lately. Take a look: GNU gdb 4.17 Copyright 1998 Free Software Foundation, Inc. GDB is free software, covered by the GNU General Public License, and you are welcome to change it and/or distribute copies of it under certain conditions. Type "show copying" to see the conditions. There is absolutely no warranty for GDB. Type "show warranty" for details. This GDB was configured as "i586-pc-linux-gnu". (gdb) handle nostop SIGSEGV SignalStop Print Pass to program Description SIGSEGV Yes Yes Yes Segmentation fault (gdb) handle noprint SIGSEGV SignalStop Print Pass to program Description SIGSEGV Yes Yes Yes Segmentation fault Is there anything I'm missing, or a gdb bug?
