I think there is potentially a slightly different cause of the above problem. During the introduction of the Altivec code, the blit_table struct field 'alpha' got changed from a straightforward enum to a bitmask, which makes perfect sense by itself. However, now the table driven blitter selection code in SDL_CalculateBlitN() can choose the wrong blitters when searching for a NO_ALPHA blitter because of the following code: int a_need = 0; ... (a_need & table[which].alpha) == a_need && When searching through the normal_blit_2[] table, a SET_ALPHA blitter (like Blit_RGB565_ARGB8888) can now be selected instead of a NO_ALPHA one, causing alpha channel bits to appear in a non-alpha destination surface. I suppose this could theoretically be an indirect cause of the segfault mentioned above. I *think* this can be fixed by changing to int a_need = NO_ALPHA;

.TH "SDL_EnableKeyRepeat" "3" "Tue 11 Sep 2001, 22:59" "SDL" "SDL API Reference" 
.SH "NAME"
SDL_EnableKeyRepeat\- Set keyboard repeat rate\&.
.SH "SYNOPSIS"
.PP
\fB#include "SDL\&.h"
.sp
\fBint \fBSDL_EnableKeyRepeat\fP\fR(\fBint delay, int interval\fR);
.SH "DESCRIPTION"
.PP
Enables or disables the keyboard repeat rate\&. \fBdelay\fR specifies how long the key must be pressed before it begins repeating, it then repeats at the speed specified by \fBinterval\fR\&. Both \fBdelay\fR and \fBinterval\fR are expressed in milliseconds\&.
.PP
Setting \fBdelay\fR to 0 disables key repeating completely\&. Good default values are \fBSDL_DEFAULT_REPEAT_DELAY\fP and \fISDL_DEFAULT_REPEAT_INTERVAL\fP\&.
.SH "RETURN VALUE"
.PP
Returns \fB0\fR on success and \fB-1\fR on failure\&.
