This makes sense: gdb has not yet been updated to reflect any changes made
since mspgcc4. One of those changes was the semantics of the value stored
in the frame pointer; see
http://www.mail-archive.com/[email protected]/msg09775.html
.
If somebody would file a tracker ticket along with an example program and
instructions for reproducing the problem (seriously: I almost never use gdb
for embedded development) it'll encourage me to look at it. But since I
expect the 20-bit changes will have a significant impact on the dwarf2 data
used for debugging, gdb updates will probably be delayed until the compiler
updates have been completed.
There's a very small but non-zero probability that a simple offset fix could
be applied now, if somebody else would care to look at it.
