[gmx-users] Re: Single precision Compilation error (Tandia, Adama)

[Pim Schravendijk]

This seems to be a Tru64 specific problem.
When looking at:

I find, amongst others:

PROBLEM:  (QAR 51448) (Patch ID: OSF405-400187)
********
This patch fixes a crash in the DEC C compiler that occurs when compiling 
a
structure whose tag is longer than 256 characters.  The problem occurs 
only
when compiling with debug symbols (-g). Below is an example of a program 
that
will cause this crash.
% cat test.c
#define a(x) x##x##x##x##x##x##x##x##x##x##x##x##x##x##x##x
struct a(XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX);
% cc -g test.c
cc: Fatal: A memory access violation (bus error or segmentation fault)
has occurred.  Please submit a problem report.

Maybe you should try a newer compiler version. 

Greetings, Pim
