-------------------------
texture3D failed to link in vertex shader, error: Too many vertex shader texture samplers.
the case at the attached can reproduce this issue.

System Environment:
--------------------------
Libdrm:         (master)2.4.29-3-gef20301a11afae50bfe127002913dbd0b81ddccc

Xf86_video_intel:(master)2.17.0-193-g34cfa15e522ba486d591d37f37d494e399f70354

with the latest mesa to verify, the issue can't be reproduced.

Similar to Bug 43360

Verified the functionality using following shaders:
static const char *vertShaderText =
        "uniform sampler3D tex3D;\n"
        "varying vec4 texcolor;\n"
        "void main()\n"
        "{\n"
        " gl_Position = gl_ModelViewProjectionMatrix * gl_Vertex;\n"
        " texcolor  = texture3D(tex3D, gl_MultiTexCoord0.xyz);\n"
        "}\n";


static const char *fragShaderText =
        "varying vec4 texcolor;\n"
        "void main()\n"
        "{\n"
        " gl_FragColor = vec4(texcolor.xyz, 1.0);\n"
        "}\n";

Seems like nothing need to be done for this bug.

All of bug #29522, bug #43359, and bug #43360 should be fixed by the recent addition of vertex texture support to the i965 driver.
