we are facing problem in executing dot binary on AIX5.1. Customer compiled it
using GCC 3.2.2 successfully, when he tried executing it. It gave me
segmentation fault on startup.
The same code has been compiled and executed on other platforms (HP 11 i,
Solaris 2.9, windows 2000 )

This is not nearly enough information for us to reproduce, lest fix
the problem. Please review

to see what we need and provide us with the missing information.

I downloaded gcc3.2.2 compiler from gnu site and installed it in my home
directory wit default settings.
Compiler version : gcc3.2.2
Machine : AIX5.1
I compiled the source code of graphviz which is available on
Here is the link from where you can download graphviz-1.8.10 source
code.
http://www.graphviz.org/pub/graphviz/ARCHIVE/
and after compilation when i ran the executable "dot" i got segmentation fault.
The same bug was filed against graphviz-1.8.10. According to graphviz team it
seems a compiler problem.
Here in thi link report is avaliable

We have problem at run time and the reported error is seen, when we ran
the "dot" application.
This not being compile time problem, we do not know, what command line should
be send as it is asked in http://gcc.gnu.org/bugs.html .
Further, the same bug is reported for "dot" application on graphviz site and
there it was analyzed to be compiler problem. ( This is the link, for your
info http://www.research.att.com/~erg/graphviz/bugs/b294.html )
Just to rule out, we have builded this "dot" application on gcc3.3 compiler,
also we builded it on gcc2.9 (the one which is available on IBM Toolbox site),
but still we get the same error.
We have tryed in every possible way and in every angle.
If any more info is required, let us know.
We want this to get resolved quickly and any thoughts, suggestions, are
wellcome.
Thanks,
Yuvraj.

To add to what Andrew said, we really are unlikely to be able to fix a bug without a small(ish) self-
contained system. If the bug is in gcc, then we need to know _exactly_ how it was built, so that we
can reproduce it.

We have got solution, and "dot" executable is running without any problem
after building and linking with IBM C Compiler ( /usr/vac/bin/cc).
I have downloaded the patch for gcc3.3 and builded gcc with this patch, which
adds options -mnatural-align to gcc, builded "dot" with two options. Check
this link
http://gcc.gnu.org/ml/gcc-patches/2003-04/msg02222.html .
But that didn't help, I was still getting core dump at runtime. ( Core dump
was because of alignment of structure members, and accessing invalid memory
address by structure pointer.) Check out this link for support of this
assumption,
http://developer.apple.com/documentation/DeveloperTools/Conceptual/MachORuntime
/2rt_powerpc_abi/chapter_3_section_3.html
And analyzing the core with gdb also support the assumption.
Then, using the IBM C Compiler for building the "dot" source and even third
party libs, solved the problem.
Thanks for your time.
