# Pck.A is an array that embeds elements with variable size so compilers will
# emit DWARF attributes such as DW_AT_byte_stride to tell GDB how to fetch
# individual elements.  Array stride is also a way to describe packed arrays:
# make sure we do not consider Pck.A as a packed array.
gdb_test "ptype pck.a" "array \\(1 \\.\\. 2\\) of pck\\.r_type"

# Make sure this also works with a type from a fully evaluated value.  During
# evaluation, dynamic types can be "resolved" so GDB internals could "forget"
# that elements have variable size.  Fortunately, type resolution of array
# elements happens only when processing individual elements (i.e. the resolved
# array type is still associated to the dynamic element type), so the following
# is supposed to work.
