Program received signal SIGSEGV, Segmentation fault. [Switching to Thread -1208236352 (LWP 25396)] 0x00fa4afb in run_texnorm_stage (ctx=0x8ce54e0, stage=0x8e81b58) at savagerender.c:251 251 GLboolean normalizeS = (texObj->WrapS == GL_REPEAT); (gdb) print texObj $1 = (struct gl_texture_object *) 0x0 (gdb) print reallyEnabled $2 = 0 (gdb) print i $3 = 1
is this you asking for ? anything that I can do ?
And this patch works! yes
Thanks,
