on Google Pixel (both on android 7.1 and 9.0) with Adreno (TM) 530 Vendor 5143 Device 5030004 Driver 512.313.0 the attempt to create even a simplest compute pipeline crashes in driver.  the error is

SIGSEGV (signal SIGSEGV: invalid address (fault address: 0x4))

and the callstack is

<unknown function> 0x00000000e6337b56

<unknown function> 0x00000000e6337206

<unknown function> 0x00000000e5f4f526

So basically upgrading android didn't change anything. Would appreciate any hints. Thanks!

here's the source for the shader

OpCapability Shader

%1 = OpExtInstImport "GLSL.std.450"

OpMemoryModel Logical GLSL450

OpEntryPoint GLCompute %2 "main" %gl_GlobalInvocationID

OpExecutionMode %2 LocalSize 8 8 1

OpDecorate %4 DescriptorSet 1

OpDecorate %4 Binding 0

OpDecorate %gl_GlobalInvocationID BuiltIn GlobalInvocationId

%void = OpTypeVoid

%6 = OpTypeFunction %void

%uint = OpTypeInt 32 0

%v3uint = OpTypeVector %uint 3

%int = OpTypeInt 32 1

%int_0 = OpConstant %int 0

%11 = OpTypeImage %int 3D 0 0 0 2 R32i

%_ptr_UniformConstant_11 = OpTypePointer UniformConstant %11

%4 = OpVariable %_ptr_UniformConstant_11 UniformConstant

%_ptr_Input_v3uint = OpTypePointer Input %v3uint

%gl_GlobalInvocationID = OpVariable %_ptr_Input_v3uint Input

%2 = OpFunction %void None %6

%14 = OpLabel

%15 = OpLoad %v3uint %gl_GlobalInvocationID

%16 = OpLoad %11 %4

OpImageWrite %16 %15 %int_0

Were you able to fix the problem? I am having the same problem when using compute shader.

Are you using DXC compiler or GlslangValidator? I am using DXC.
