I have finished the compilation of the debug mesa lib ( with CFLAG=-g )
now the result when gdb stops in breakpoint in meta.c, line 2258 :
(gdb) print ctx->_ImageTransferState
$4 = 1
(gdb) print ctx->Fog.Enabled
$5 = 0 '\000'
now ctx->_ImageTransferState is set to "1"
the conditionnal was :
if (ctx->_ImageTransferState ||
ctx->Fog.Enabled) {
fallback = GL_TRUE;
}
then I set another breakpoint:
break s_span.c:1326
the variable colorType is still set to "0" just before the crash :
(gdb) print colorType
$3 = 0
that's why this assertion fails in line 1326 :
GLchan rgbaSave[MAX_WIDTH][4];
struct swrast_renderbuffer *srb = swrast_renderbuffer(rb);
GLenum colorType = srb->ColorType;
assert(colorType == GL_UNSIGNED_BYTE || colorType == GL_FLOAT);
