SEGV/GNAT-3.13p/Florist/RedHat-7.1

[matthewmajka@mac.com (Matt Majka)]

Hi!

I was wondering if anyone else has run into this and has a solution/workaround.
I'm using gnat-3.13p on a fresh RedHat-7.1 installation.  I've built
florist-3.13p
and installed it as well.  The GNAT compiler seems to be working fine with some
test programs I brought over from Solaris.  However, as soon as I try to use the
POSIX bindings, the program causes a segmentation fault prior to executing any
of my code (I don't even think it makes it to the elaboration stage). 
I've included
my simple test program and the output of GDB when I ran it with the resulting
core file.  I'm trying to port some serial IO code I wrote under a proprietary
real-time Unix to Linux and the low-level code makes extensive use of the
IEEE binding interface.  I tried generating the binder file in C to see if
I could
get a better feel for what is going on, but I had the same result.

Thanks!

Matt
