Having trouble setting breakpoint

[bluemooseking]

Hi,

I'm using GDB with MinGW on WinXP. I've created a DLL that I'm trying
to debug in GDB. I get an error however when I try to set a
breakpoint ... below is a transcript of the problem. Any ideas how I
can find out more about this Input/Output error I'm having???

Jon
