fortran: Fix ICE on pr96024.f90 on big-endian hosts [PR96024]
|
|
|
|
The pr96024.f90 testcase ICEs on big-endian hosts. The problem is
|
|
that length->val.integer is accessed after checking
|
|
length->expr_type == EXPR_CONSTANT, but it is a CHARACTER constant
|
|
which uses length->val.character union member instead and on big-endian
|
|
we end up reading constant 0x100000000 rather than some small number
|
|
on little-endian and if target doesn't have enough memory for 4 times
|
|
that (i.e. 16GB allocation), it ICEs.

* primary.c (gfc_convert_to_structure_constructor): Only do
|
|
constant string ctor length verification and truncation/padding
|
|
if constant length has INTEGER type.
