print *,readInArray

deallocate(readInArray)

end subroutine main

 

 

 

 

I believe I have found an error in the intel ifort compiler (the 2017 version). I have tested this with ifort 16 and the bug is not there.

I have written the above program to demonstrate this.

When I run the following:

 

ifort error.f90 -traceback -g -debug all -warn all -check bounds -check format -check output_conversion -check pointers  -ftrapuv -check all -gen-interfaces -warn interfaces 

 

I get the following error: 

 

forrtl: severe (194): Run-Time Check Failure. The variable 'var$76' is being used in 'error.f90(36,1)' without being defined

Image              PC                Routine            Line        Source             

a.out              000000010D72464C  _main_                     36  error.f90

a.out              000000010D725574  _MAIN__                     2  error.f90

a.out              000000010D723CAE  Unknown               Unknown  Unknown

 

 

As already mentioned. This does not happen in the 2016 version.
