Confirmed, reduced to:
typedef long unsigned int size_t;
__extension__ typedef int __ssize_t;
typedef __ssize_t ssize_t;
extern ssize_t read (int __fd, void *__buf, size_t __nbytes);
struct QString
{
QString();
};
class QDataStream;
struct KSycocaEntry
{
static void read( QDataStream &s, QString &str );
KSycocaEntry( QDataStream &_str, int offset )
{
read(_str, mPath);
}
QString mPath;
};
: Search converges between 2004-09-27-014001-trunk (#563) and 2004-09-27-161002-trunk
(#564).
A recent regression.

Here the reduced a little further:

class QString{};
struct KSycocaEntry
{
static void read( int &s, QString &str );
KSycocaEntry( int &_str, int offset )

Also a 3.4 regression:
: Search converges between 2004-09-27-004002-3.4 (#82) and 2004-09-28-004001-3.4 (#83).
Caused by the patch which fixed PR 17585.
