------- Comment #2 from burnus at gcc dot gnu dot org 2010-01-13 22:26 ------- I think there is an off by one problem in the call to assign_lv_real; that also matches the problem shown by gdb:
Breakpoint 2, assign_lv_real (lefthandside=Cannot access memory at address 0x1e141b0 (gdb) pt lefthandside type = real(kind=4) (gdb) p righthandside $2 = ( 42 ) Looking at the dump, one finds: ! data.2 is memcopy of parm.1.data = table->realdata.data atmp.2.data = (void * restrict) data.3; atmp.2.dim[0].stride = 1; D.1596 = -atmp.2.dim[0].stride; D.1598 = NON_LVALUE_EXPR <atmp.2.dim[1].stride> + D.1596; D.1599 = NON_LVALUE_EXPR <table->realdata.dim[1].stride> + D.1567; assign_lv_real (&(*(real(kind=4)[1] * restrict) atmp.2.data)[S.4 + D.1598], &D.1601); While table->realdata.dim[...].stride has for both [0] and [1] the stride set to 1, atmp.2 only has "atmp2.dim[0].stride" set thus atmp.2.dim[1].stride is either 0 or some other random value. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42736
