And just to show that:

Compiling for 32 bit, and using an **older** gdb on Windows:

GNU gdb 6.7.50.20071127
Current language:  auto; currently pascal
(gdb) p a
$1 = {ab = 0, static d = 3}


It was able to print that for records. (well it gets the value wrong)
(I did not find the version that worked for classes too, though older 
v.6 did not crash, but just say "optimized out" for the constant)

And again, making gdb believe its a "c" app, and a lot more suddenly works.
