Summary: r300g: segfault in r300_draw_arrays_immediate Product: Mesa Version: git Platform: x86-64 (AMD64) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r300 AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: wixorpeek@gmail.com CC: maraeo@gmail.com
A bug was introduced between 5a01361ceaf29 and dc578188fae099 causing reproducible segmentation fault with latest svn Blender (the code excercices fixed-function pipeline and draws a handful of primitives with begin-end).
Core was generated by `./blender'. Program terminated with signal 11, Segmentation fault. #0 0x00007f5b484c2785 in memcpy () from /lib/libc.so.6 (gdb) bt #0 0x00007f5b484c2785 in memcpy () from /lib/libc.so.6 #1 0x00007f5b40def53f in r300_draw_arrays_immediate (r300=<value optimized out>, mode=<value optimized out>, start=<value optimized out>, count=<value optimized out>) at r300_render.c:430 #2 0x00007f5b40df15c6 in r300_draw_vbo (pipe=0x256a5e0, info=0x7ffff8ef3d70) at r300_render.c:803 #3 0x00007f5b40ead410 in st_draw_vbo (ctx=<value optimized out>, arrays=<value optimized out>, prims=<value optimized out>, nr_prims=8, ib=0x0, index_bounds_valid=<value optimized out>, min_index=0, max_index=14) at state_tracker/st_draw.c:715 #4 0x00007f5b40eaa702 in vbo_exec_vtx_flush (exec=0x2620b00, unmap=1 '\001') at vbo/vbo_exec_draw.c:383 #5 0x00007f5b40ea7afc in vbo_exec_FlushVertices_internal (ctx=<value optimized out>, unmap=28 '\034') at vbo/vbo_exec_api.c:912 #6 0x00007f5b40ea7b4a in vbo_exec_FlushVertices (ctx=0x2577b28, flags=1) at vbo/vbo_exec_api.c:946 #7 0x00007f5b40e5315e in _mesa_MultMatrixf (m=0x260cb94) at main/matrix.c:383 #8 0x00000000006a72f9 in ED_view3d_init_mats_rv3d (ob=<value optimized out>, rv3d=0x25f4728) at source/blender/editors/space_view3d/space_view3d.c:174 #9 0x00000000006c1d4d in draw_object (scene=<value optimized out>, ar=<value optimized out>, v3d=<value optimized out>, base=<value optimized out>, flag=<value optimized out>) at source/blender/editors/space_view3d/drawobject.c:5743 #10 0x000000000069f3f6 in view3d_main_area_draw (C=<value optimized out>, ar=0x25f45b8) at source/blender/editors/space_view3d/view3d_draw.c:2428 #11 0x0000000000842865 in ED_region_do_draw (C=0x21c1b28, ar=0x25f45b8) at source/blender/editors/screen/area.c:340 #12 0x000000000066e59e in wm_method_draw_overlap_all (C=0x21c1b28, win=0x25dd0d8, exchange=0) at source/blender/windowmanager/intern/wm_draw.c:244 #13 0x000000000066ede5 in wm_draw_triple_fail (C=0x21c1b28) at source/blender/windowmanager/intern/wm_draw.c:418 #14 wm_method_draw_triple (C=0x21c1b28) at source/blender/windowmanager/intern/wm_draw.c:578 #15 wm_draw_update (C=0x21c1b28) at source/blender/windowmanager/intern/wm_draw.c:769 #16 0x0000000000674008 in WM_main (C=0x21c1b28) at source/blender/windowmanager/intern/wm.c:348 #17 0x00000000006611ea in main (argc=1, argv=0x7ffff8ef4628) at source/creator/creator.c:1266
