Summary: attribute((mode(byte))) in a typedef produces wrong
debug information
Product: gcc
Version: 4.5.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
AssignedTo: unassig...@gcc.gnu.org

Test case
The attached test case shows attribute((mode(byte))) used to produce enums that
are one byte long rather than the usual 4.
The compiler actually sees the correct value of sizeof() but GDB (7.2) does
not. This can be seen by compiling the test case; gdb shows the value of s1
as 1, but sizeof(foo) as 4.
When compiled with GCC 3.3.3, s1 and sizeof(foo) both show up as 1, as
expected.
