[Mesa3d-dev] Run-time roblem with current (trunk) CVS version

[<jo...@hr...>]

Hi all,

I tried the current CVS version of Mesa to run some of the demo's of the
package xlockmore on my OpenVMS system. In some modes (i.e. cage,morph3d,
stairs ) I get a crash (traceback is at the end of this mail). The line 51887
of ss_triangle.c can also be 51889 and points to line 146-148 of ss_tritmp.h:

146	    if (VB->SecondaryColorPtr[0]) {
145	       GLfloat (*vbspec)[4] = VB->SecondaryColorPtr[0]->data;
146	       SS_SPEC(v[0]->specular, vbspec[e0]);
147	       SS_SPEC(v[1]->specular, vbspec[e1]);
148	       SS_SPEC(v[2]->specular, vbspec[e2]);

A "floating invalid" may indicate that VB->SecondaryColorPtr[0]->data is
allocated but not initialized. It may contain rubish instead of zero's.
Can that be the case? and if yes where should it be repaired?
