Help: my GNAT program hangs during elaboration

Help: my GNAT program hangs during elaboration

[Thierry S.]

Hi,

I have developed a small program which uses FLORIST for some low level file
access and a few other things.

But when I try to run my program, it hangs during elaboration.  See below
for the GDB backtrace output:
(gdb) bt
#0  0xffffe002 in ?? ()
#1  0x09eabee9 in system__interrupts___elabb ()
#2  0x0804b37d in adainit () at b~my_driver.2.adb:859
#3  0x0804e4ad in main (argc=1, argv=3221222916, envp=3221222924)
    at b~my_driver.2.adb:3054
#4  0x42015704 in __libc_start_main () from /lib/tls/libc.so.6

where /lib/tls/libc.so.6 is a link to libc-2.3.2.so

Florist downloaded from ACT-Europe libre: /home/tschn/florist-3.15p-src
Compiler: /usr/local/gnat-3.15p/bin
C-Library: libc-2.3.2

Any clues?
Has anybody experienced this issue before?
Do you see any incompatibility(ies) with my setup?
Is there any way for my porgram not to link in 'system__interrupts'?

I suspect that my issue is in the way I have setup/installed FLORIST.

For POSIX, do I need the threads with RH9? (I don't think so as I only want
to run a standalone program, there won't be any inter-process communication,
only some read/write into a few files).

Note: I tried with and without POSIX threads, I get the same result (my
program hangs).

Thanks in advance for any help you may be able to provide.
