[Mspgcc-users] gdb 'next' not working as expected

[KFranke <kf...@sw...>]

Hello,

I'm new to mspgcc and am having some problems with the gdb.
'next' commands always seem to take me inside function calls.
I get the same behavior using the msp430-gdbproxy and using
the 'sim' target.

I'm running binaries from mspgcc-20040723.exe from a cygwin
shell on a w2k machine.

The program was compiled with:
$ msp430-gcc -g -o test test.c -mmcu=3Dmsp430x169

gdb output follows. The last 'n' command enters the get_status()
function instead of breaking on the next line of main().

Thanks in advance,

Kurt
