>Description:
Gdb6.3 fails to download target image when a load command is issued as part of remote debug beyond first packet and erroneously displays "Memory access error while loading section xxx". This behavior is because function "load_section_callback"
in file "symfile.c" checks variable "err" after calling function "target_write_memory_partial". Variable "err" is not properly set inside "target_write_memory_partial" under all paths. See Fix for simple solution.
>How-To-Repeat:

>Fix:
Set variable err = 0; on line 1435 of "symfile.c", in
function "load_section_callback" before calling function "target_write_memory_partial". This ensures err is properly initialized on return for paths which don't set err explicitly.
