Please read the manual:
http://sourceware.org/gdb/current/onlinedocs/gdb/Inline-Functions.html
"For gdb to support inlined functions, the compiler must record
information about inlining in the debug information â gcc using the
dwarf 2 format does this, and several other compilers do also. gdb
only supports inlined functions when using dwarf 2. Versions of gcc
before 4.1 do not emit two required attributes (`DW_AT_call_file' and
`DW_AT_call_line'); gdb does not display inlined function calls with
earlier versions of gcc. It instead displays the arguments and local
variables of inlined functions as local variables in the caller. "
I guess you have two solutions:
1 ) Update your compiler to gcc-4.4.3
2 ) Tell your compiler *not* to inline function, using -fno-inline
