Hi, I tried to compile coefu.f with f77. However, a fatal error occured at compile. I placed a source file and include files at the following directory. You may reproduce the problem. Please tell me how to fix it.

Until this can be fixed, for a workaround try different compiler options or isolate the source code that may be tripping the compiler. $ dir tkov51::pub$:[temp]dfant.zip Directory TKOV51::PUB$:[TEMP] DFANT.ZIP;1 Total of 1 file. $

We'll take a look at it and get back to you. /Stan | |||||
| 1226.2 | Memory layout; fixed in current compiler | TLE::MENARD | new kid on the COMMON block | Tue Mar 18 1997 14:16 | 27 |
We have brought your file over, and have reproduced the problem.
With the NT compiler we occasionally had a problem where we would try
to access (read) memory that had not yet been allocated. This showed up
when we rearranged the symbol table layout to try and use memory more
efficiently; temporary symbols created by the compiler wouldn't use as
much space as "real" symbols declared by the user. Unfortunately, sometimes
the compiler would look for a field that was outside of the range of the
temporary symbol.
I have confirmed that your problem is one of these, and that we have
fixed it in the current compiler (it was edit 4-41 from July 96).
One possible workaround that you can use now, until a new version of the
compiler is available, is to insert a dummy variable into your symbol table
to change its configuration just enough to avoid the memory layout problem.
I editted comm1.inc and created a line: INTEGER MYDUMMY before the
EQUIVALENCE statement, and the program compiled to completion.
Or, you could become part of the field test for our next release of the
Alpha NT compiler, and have access to newer software that way. If you
are interested in this, just let us know and we can get you signed up.
Thank you for the good example, and for the files to reproduce it,
- Lorri
