[Libav-user] Problem debugging ffmpeg.c in eclipse+ cygwin gdb

[Aditya]

This is my build configuration for ffmpeg.c
http://pastebin.com/PFM4K4xF

you can view from the build configuration generated .
 i have set posix style
paths for the ffmpeg source.

the debug/run arguments are as
 -i Debug/sample2.mpg  -ab 56k -ar 22050 -b 512k
-r 30 -s 320x240 Debug/out2.flv

this all works fine when  i run the program. the output file is generated.

but when i try to debug the ffmpeg.c program it keeps stopping/hanging 
at certain instructions and the step over option disables.

like show_banner() and parse_options. ( when i commented out show_banner() it
stoped at parse_options.)

what is this error ? How do i resume stepping over instructions.
