Bug ID: 83246
Summary: internal compiler error or loader problem might be
related to a PARAMETER statement being in a BLOCK
Product: gcc

Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org

create scratch file in BLOCK
Using GNU Fortran 6.4.0 on Cygwin I get various errors and/or this
program runs making small changes to the test code. I only seem to
have problems if I declare a PARAMETER in a BLOCK, but I thought
that was allowed? (Really have not used BLOCK much yet).
If I have block MAKEDATA first I get loader error
>/tmp/CCALL_CYGWIN64_GFORTRAN_8008/ccQ0aELt.o: In function `dusty_corner':
>/tmp/CCALL_CYGWIN64_GFORTRAN_8008/yyy.8008.f90:28: undefined reference to
`scratch.3494'
>/tmp/CCALL_CYGWIN64_GFORTRAN_8008/yyy.8008.f90:28:(.text+0x79a): relocation
truncated to fit: R_X86_64_PC32 against undefined symbol `scratch.3494'
If I switch the order of MAKEDATA and MAKEDATAP blocks I get
> MAKEDATA: block

If I comment out the first write statement ("BLOCK TESTS") the program works
or
If I comment out block MAKEDATAP the program works
