The information in this article applies to:


 * Microsoft Fortran PowerStation for Windows 95 and Windows NT 4.0

This article was previously published under Q149147



SYMPTOMS
Assigning a value to an equivalenced variable not part of a common block in an internal subroutine when the associated equivalenced variable is part of a common block causes the following compile-time ASSERT failure message to be generated:

Assertion failed: base->key.be_key != 0, file err_genex.c, line 2828 abnormal program termination



RESOLUTION
Do one of the following to work around the problem:


 * Redeclare the common block and equivalence in the internal procedure. -or-


 * Do not assign a value to the non-common block equivalenced variable.



STATUS
Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.



Sample Code to Illustrate Problem
! Compile options needed: none

program test real r         integer i          common /theblock/ i          equivalence (r,i) call b         print *, r      contains subroutine b ! uncomment the next 4 lines for work-around !             real r !              integer i !              common /theblock/ i !              equivalence (r,i) r = 1.0         ! This line causes an ASSERT failure end subroutine b     end program test
