single stepping mips remote programs built with gcc 4.0

Hi, I have a version of gdb from CVS on 8/29/2005. I have configured with the target as mips-elf and the host as cygwin and I am using it to connect to a remote mips system. All of my programs I am trying to run remotely have been built with GCC 4+. I am single stepping through code where part of it consists of something like the following in the disassembly listing:

00003dac <initialize()>:
00003dac: 24040001 li a0,1
00003db0: 08000deb j 000037ac <setArraySize(int, int)>
00003db4: 24050001 li a1,1

00003db8 <getCurrentBuffer2(int&)>:
00003db8: 3c02bd00 lui v0,0xbd00

When stopped at the beginning of the function, I can tell by looking at the remote protocol debug output that a breakpoint is being set in memory at the location of getCurrentBuffer2, not setArraySize. We suspect that this may have to do with GCC 4+ doing straight jumps to other functions and not jump and link followed by jump register to leave the function. Has anyone else encountered this or found a solution?

Thank you,

Sarah Newman
