I gave it a try. I see the error, but a bit too early. That's because
I have a stub in the middle of my call stack. Here is what I get now:
(gdb) bt
#0 simple.break_me () at simple.adb:27
#1 0x0000a2cc in simple.caller (<_task>=0x4001c3a0) at simple.adb:21
#2 0x0000a268 in simple__callerB___2 () at simple.adb:18
#3 0x0000a268 in simple__callerB___2 () at simple.adb:18
warning: Previous frame identical to this frame (corrupt stack?)
(this was with 6.3, do you think HEAD would behave better?)
