type variable pre-allocated + error

Dear all,

I am probably doing something that is not possible.

I have created this variable in a general module:

  TYPE tresultVar
     REAL     :: pmean   ! posterior mean for variable i
     REAL     :: PM(4)    
     REAL     :: pstd    ! posterior std deviation
     REAL     :: PR(4)
     REAL     :: NSET(4) !    
  ENDTYPE

After that I call a subroutine as:

CALL APMSUB(nVar,resapmVAR,res1RESULTSVAR,res2RESULTSVAR)

and the subroutione look like:

SUBROUTINE APMSUB(nVar,resultGV,result1V,result2V)
  USE VARS_DIAGNOSTIC
  USE mod_alngam
  IMPLICIT NONE
  INTEGER             :: nVar
  TYPE(tresultVar)    :: resultGV(nVar)
  TYPE(tresultVar)    :: result1V(nVar)
  TYPE(tresultVar)    :: result2V(nVar)

The var type in in the module  VARS_DIAGNOSTIC

Where I write:

WRITE(*,*) size(resultGV(iVar)%PM)

I get, as expected: 4

However, if a write:

WRITE(*,*) resultGV(iVar)%PM

I get an error.

What am I doing wrong?

I am trying to do something that is not possible?

Thanks for any helps

Diedro, this is not s a complete code. All examples I tried to make from it, compiled. You get an error? What kind of error? A compilation error, a runtime error, the computer froze? You have to give more information.

Dear Juergen R. Dear all,

you are right. I get the following error:

forrtl: severe (174): SIGSEGV, segmentation fault occurred
Image              PC                Routine            Line        Source             
a.out              0000000000460BBD  Unknown               Unknown  Unknown
libpthread-2.23.s  00007F69D3F49390  Unknown               Unknown  Unknown

 

Really thanks for any kind of help

That is a little more information, but not yet enough. So the program compiles and then exhibits a runtime error. The fact that the pthread library appears there raises my suspicion that you are linking some external tool/library into your program which uses more than one thread, and then you do a write operation. But possibly one needs a full reproducer here.

Dear Juergen R., dear all,

I have no  external tool/library. However, I will try to make a simple test case by the end of tomorrow.

Thanks for the suggestions,
Diedro

Dear Juergen R., dear all,

I have understood the error doing the test case. So really thanks for your suggestions.
I attach the test case hoping that it can help in understanding this post,

again, really really thanks

@diedro,

I'll suggest you provide specific details on the code you are using and steps you are taking to compile and link and execute to get prompt and relevant guidance.  Here's an example using a Windows console of what one can do:

C:\Temp>type VARS_DIAGNOSTIC.f90
MODULE VARS_DIAGNOSTIC
  !
  !
  TYPE tresultVar
     REAL     :: PM(4)
  ENDTYPE
  !
  !
ENDMODULE

C:\Temp>type MOD_TEST_SUB.f90
MODULE MOD_TEST_SUB
 CONTAINS

 SUBROUTINE TEST_SUB(nn,VARIN)
 USE VARS_DIAGNOSTIC
 IMPLICIT NONE
 INTEGER :: nn
 TYPE(tresultVar) ::  VARIN(nn)

 VARIN(1)%PM(1) = 1.

 WRITE(*,*) VARIN(1)%PM

 ENDSUBROUTINE
ENDMODULE
