Brain fart alert

[Nicolas <nikos42@xxxxxxxxx>]

Hello,

I tried using pahole, but I get a brain fart alert with the file
attached (which is an extract from stdio.h). I'm running dwarves 1.10,
libdw1 0.152 and g++ 4.6.1, on i386.

Here is what I get:

$ g++ -Wall -g -c brainfart.cpp -o brainfart.o && pahole brainfart.o
class ios_base {
	enum _Ios_Openmodeconst    in;                   /*     0     4 */
	typedef enum _Ios_Fmtflags fmtflags;


	/* size: 1, cachelines: 1, members: 1 */
	/* padding: 65533 */
	/* last cacheline: 1 bytes */

	/* BRAIN FART ALERT! 1 != 4 + 0(holes), diff = -3 */

};

Moreover, on amd64, pahole segfaults if I do the same (with dwarves
1.10, libdw1 0.152, g++ 4.6.3).

Any ideas?

Thanks a lot,
Nicolas
