finally I succeed to get the value of "colorType",
I set a breakpoint like this in gdb :
break s_span.c:1326
after that gdb manages to reach the breakpoint :
Breakpoint 1, _swrast_write_rgba_span (ctx=ctx@entry=0xbc60648,
span=span@entry=0xbfffe750)
at swrast/s_span.c:1326
1326 assert(colorType == GL_UNSIGNED_BYTE ||
then I can see the value of colorType:
(gdb) print colorType
$1 = 0
colorType is set to zero here
