Summary: Segmentation fault with indirect rendering
Product: Mesa
Version: 7.6
Platform: All
OS/Version: All
Status: NEW
Severity: major
Priority: medium
Component: GLX
AssignedTo: mesa3d-dev@lists.sourceforge.net
ReportedBy: markus.flesch...@x-software.com
When using indirect rendering and the program "framebufferobject" from the Qt
demos a segmentation fault happens.
The segmentation fault is in src/glx/x11/indirect_vertex_array.c:
__glXPushArrayState(), because glPushClientAttrib(GL_CLIENT_VERTEX_ARRAY_BIT)
is called twice or more times.
The solution is to change src/glx/x11/indirect_vertex_array.c, line 293
(function glXInitVertexArrayState) from:
arrays->stack = malloc(sizeof(struct array_stack_state)
* arrays->num_arrays);
to:
arrays->stack = malloc( sizeof( struct array_stack_state )
* arrays->num_arrays
*__GL_CLIENT_ATTRIB_STACK_DEPTH);
