[bug-cflow] possible reason for attribute confusiong

[Britton Kerin]

The DBUS_ALLOC_SIZE mentioned in the last bug report is defined like so:

#define DBUS_ALLOC_SIZE(x) __attribute__((__alloc_size__(x)))
#define DBUS_MALLOC     __attribute__((__malloc__))

DBUS_EXPORT is empty for me

perhaps the problem is related to the nestedness of the argument in
DBUS_ALLOC_SIZE(x)

This might also explain why adding --symbol __alloc_size__:wrapper
fixes (or at least masks) the problem.
