The attached patch fixes an out of bound write to memory allocated
with alloca() on the stack. This rarely ever happened because on
one hand -fbounds-check needs to be enabled, and on the other hand
alloca() used to allocate a few bytes extra most of the time so
most of the time the excess write did no harm.

* trans-array.c (gfc_conv_array_ref): Fix allocation of diagnostic
