First  I  wrote about this issue to Florian Klampfl, but looks like he
is  on  vacation  or something like that - there have been no messages
from him in mailing list for about a week. So I am repeating, now with
mailing list.

I  am  author  of the ALGLIB - open source numerical analysis library.
ALGLIB  contains  C++,  C#, VB6 and Delphi code (same functionality in
different  languages).  ALGLIB  2.1.2  is tested under Win32 compilers
only,  but  next  release will be tested under wide set of Windows and
Linux compilers (both x86 and x86_64).

Since Delphi is Windows-only and have no free command line compiler, I
want  to  make  transition  to the FreePascal compiler. Targeting free
cross-platform   compiler  seems  better  alternative  than  targeting
proprietary  x86+Windows  only compiler without even free command-line

I've  planned  to  announce  full  FPC  compatibility  in ALGLIB 2.2.0
However, I have problems with x86_64 FreePascal for Linux (bug #15206,
http://mantis.freepascal.org/view.php?id=15206 - compiler crashes when
trying to compile ALGLIB).

May  I  ask  when  are you going to make next FPC release and will bug
#15206  be  fixed in that release? Currently it is the only thing that
stops  me  from  declaring  full FreePascal compatibility for upcoming
ALGLIB 2.2.0

Another question: are you interesting in using ALGLIB as a part of the
FPC  test  suite?  Large  numerical  analysis  libraries  are  good in
triggering  compiler  bugs  (for example, GMP and MPFR have discovered
many  bugs  in  GCC).

I  can help you with testing new FPC releases on x86/x86_64 platforms,
if you want.
