Invoking a Postmortem Report

A postmortem report may be invoked by any of the following:

an error detected as a consequence of using the -CA, -CB, -CS, -CU, -CV or -C options
a call on abort
an allocation error
an invalid assigned label
an input-output error
an error reported by a mathematical procedure
a signal generated by a program error such as illegal instruction
an error reported by an intrinsic procedure

Postmortem Report Conventions

The following conventions are used in postmortem output:

A variable var declared in a module mod appears as mod.var.
A module procedure proc in module mod appears as mod$proc.
The fields of a variable var of derived data type are preceded by a line of the form var%.

Example

In this example, the command line

prompt>ifc -CB -CU -d4 sample.f

is used to compile the program that follows. When the program is executed, the postmortem report (follows the program) is output, since the subscript m to array num is out of bounds.

The Program

1 module arith
2 integer count
3 data count /0/
4
5 contains
6
7 subroutine add(k,p,m)
8   integer num(3),p
9
10   count = count+1
11   m = k+p
12   j = num(m)
13   return
14 end subroutine
15
16 end module arith
17
18 program dosums
19 use arith
20 type set
21    integer sum, product
22 end type set
23
24 type(set) ans
25
26 call add(9,6,ans%sum)
27
28 end program dosums
