A belated thanks for the bugreport!

Looks like. I get the wished-for segfault for the second program of comment 0.
The assembler also looks OK, but I have to admit that I am not really an
assembler person.
For the simpler
module m
integer, parameter :: xxx(*) = [1,2,3,4]
end module m
one gets now the following:
.globl __m_MOD_xxx
.section .rodata
.align 16
.type __m_MOD_xxx, @object
.size __m_MOD_xxx, 16
__m_MOD_xxx:
.long 1
.long 2
.long 3
.long 4
Hence, I indeed see the .rodata for the correct variable.
I close this bug now - please reopen if something is still wrong.
