PR middle-end/42681
* graphite-clast-to-gimple.c (gloog_error): New static variable.
(clast_to_gcc_expression): Do not build MULT_EXPR of POINTER_TYPE_P.
Set gloog_error when such an expression failed to be built.
(translate_clast): Early return when gloog_error is set.
(gloog): Clear gloog_error. When gloog_error is set, call
set_ifsese_condition to enable the original code. Return the status
of the code generation based on gloog_error.
* sese.c (set_ifsese_condition): New.
* sese.h (set_ifsese_condition): Declared.
* testsuite/g++.dg/graphite/pr42681.C: New.
