Static variables are persistent for the duration of the program and are stored on the heap. The uninitialized ones are located in the bss section of the heap.

eg:
static int temp1;

}
In this code segment, are both temp1 and temp2 stored in .bss?
temp1 and temp2 will be located in the bss section of the heap as would be gtemp1 unless they were explicitly initialized.

GLSHADERSTORAGEBLOCK(3G) OpenGL Manual GLSHADERSTORAGEBLOCK(3G)
NAME
glShaderStorageBlockBinding - change an active shader storage block binding
C SPECIFICATION
void glShaderStorageBlockBinding(GLuint program, GLuint storageBlockIndex, GLuint storageBlockBinding);
PARAMETERS
program
The name of the program containing the block whose binding to change.
storageBlockIndex
The index storage block within the program.
storageBlockBinding
The index storage block binding to associate with the specified storage block.
DESCRIPTION
glShaderStorageBlockBinding, changes the active shader storage block with an assigned index of storageBlockIndex in program object program.
storageBlockIndex must be an active shader storage block index in program. storageBlockBinding must be less than the value of
GL_MAX_SHADER_STORAGE_BUFFER_BINDINGS. If successful, glShaderStorageBinding specifies that program will use the data store of the buffer
object bound to the binding point storageBlockBinding to read and write the values of the buffer variables in the shader storage block
identified by storageBlockIndex.
ERRORS
GL_INVALID_VALUE is generated if attribindex is greater than or equal to the value of GL_MAX_VERTEX_ATTRIBS.
GL_INVAILD_VALUE is generated if bindingindex is greater than or equal to the value of GL_MAX_VERTEX_ATTRIB_BINDINGS.
GL_INVALID_OPERATION is generated if no vertex array object is bound.
ASSOCIATED GETS
glGet() with arguments GL_SHADER_STORAGE_BUFFER_BINDING, GL_MAX_SHADER_STORAGE_BUFFER_BINDINGS, GL_MAX_VERTEX_SHADER_STORAGE_BLOCKS,
GL_MAX_TESS_CONTROL_SHADER_STORAGE_BLOCKS, GL_MAX_TESS_EVALUATION_SHADER_STORAGE_BLOCKS, GL_MAX_GEOMETRY_SHADER_STORAGE_BLOCKS,
