>Environment:
arm-linux target running gdbserver 5.2, host running debian woody with gdb-5.2 targeted to arm-linux
>Description:
While debugging an arm binary remotely, I attempted to use the stepi command.  It worked perfectly until it hits the first conditional branch at which point gdbserver just went to the exit of the program.  I was only able to replicate it when debugging a static library (libfloat.a).

Because this bug is very difficult to replicate I do not expect it will be possible to fix unless a better means of replicating it can be found.
>How-To-Repeat:
Compile libfloat.a for strongarm target.  
Compile a simple program like "main() { float f; f=f+1.0f; }" with soft-float.
Specify remote debugging session.  
Break on main.  
Stepi into libfloat (f=f+1.0f). 
Program with run to completion on first conditional branch.
