Application crash in libifcoremd.dll 13.1 on Windows Server 2008 R2, SP1

Hi,

I am investigating a strange problem with just one of our customers on a Windows Server 2008 R2, SP1 machine.

This is an excerpt of the code:

       CHARACTER*80 ICBUFF
       INTEGER    MMBUFF
       PARAMETER (MMBUFF = 20)
       INTEGER    LFBUFF(MMBUFF)
       REAL       BFBUFF(MMBUFF)
       EQUIVALENCE (LFBUFF,BFBUFF)
       READ (ICBUFF,FMT='(BN,76X,I4)',ERR=9020)  LFBUFF(1)

Crash:

Unhandled exception at 0x05C70CCE (libifcoremd.dll) in crashdump.dmp:
0xC0000005: Access violation reading location 0x45C70F80.

Version of libifcoremd.dll:
13.1 - 101 (Update A)

I could not reproduce this crash on one of our machines and it happens with just one customer only and only with this library version (newer ones not tested).

Is there any known issue, a registry setting or perhaps a problem with permissions involved?
