Of the two places, having the description of 'frame' and 'select-frame'

Attempt to take address of value not located in memory.
The problem is that in EVAL_AVOID_SIDE_EFFECTS mode,
eval.c:evaluate_subexp_standard always returns a not_lval value as the
result for a STRUCTOP_STRUCT operation. As a consequence, the rest of
the code believes that one cannot take the address of the returned

This patch fixes STRUCTOP_STRUCT handling so that the VALUE_LVAL

avr: Fix bugs in org/align tracking.
This commit fixes a few issues in the mechanism for passing information
about ".org" and ".align" directives from the assembler to the linker,
used by the avr target.
In the original commit
fdd410ac7a07dfb47dcb992201000582a280d8b2, there
were some mistakes when writing out information about ".align"
directives:
- An align with fill does not write out its information correctly, the
fill data overwrites the alignment data.
- Each alignment directive is recorded at the location where the
previous alignment directive should be recorded, the first alignment
directive is discarded.
In commit
137c83d69fad77677cc818593f9399caa777a0c5, the data produced by
objdump is not correct:
- It's miss-aligned due to a missing whitespace.
- The fill data for align with fill records is not displayed
correctly.
All of the above issues are addressed in this commit, and the test is
improved to cover these cases.

[Ada] Buffer overflow in ada_unpack_from_contents
This patch fixes a buffer overflow in ada_unpack_from_contents
caused by one of the previous commits. This happens when trying
to print the value of an array of variant records.
The overflow happens while trying to print one element of the array.
Because the size of each element in the array is variable, the array
has a DWARF byte_stride attribute, which makes us treat the array
as if it was packed. And during the extraction of each array element,
we try to unpack an object using the array's byte stride as the size,
into an element whose size is actually less than the stride.
This patch fixes the issue by overriding the byte-stride with
the actual element's length.

[Ada] Better handling of dynamic types in ada_value_primitive_packed_val
There is some partial handling for dynamic types in
ada_value_primitive_packed_val, but this support was added
in a fairly ad hoc way, and actually only covered the situation
where OBJ is not NULL and its contents had not been fetched yet.
In addition, even in the cases that it does cover, it doesn't make
much sense. In particular, it was adjusting BIT_SIZE and SRC_LEN,
which are properties of the data to be extracted _from_, based
on TYPE's length once resolved, which is a property of the data
we want to extract _to_.
This patch hopefully adjust this function to handle dynamic types
correctly, and in all cases. It does so by unpacking the data into
a temporary buffer in order to use that buffer to resolve the type.
And _then_ creates the resulting value from that resolved type.

That's true of expect in general, but I had missed / forgot that
