Enviroment
OS : HPUX 10.20
gnat : Version 3.09 for HPUX 10.10
Consider the following Ada code:
SPEC : delay_test.ads
package DELAY_TEST is
procedure DO_DELAY;
end DELAY_TEST;
BODY : delay_test.adb
package body DELAY_TEST is
procedure DO_DELAY is
begin
delay 0.0;
end DO_DELAY;
end DELAY_TEST;
EXECUTABLE : adi_test_delay.adb
with DELAY_TEST;
with TEXT_IO;
procedure ADI_TEST_DELAY is
begin
TEXT_IO.PUT_LINE ("Test ADI_TEST_DELAY");
end ADI_TEST_DELAY;
Compile and link with the command :
gnatmake adi_test_delay
If I run the executable adi_test_delay it crashes badly (it logs me out
of the system).
If I take TEXT_IO out it works fine.
What is the problem?
Is there a gnat version (or patch) for HPUX 10.20, and if so, where can
I get it?
Thanks for your help.

Just hazarding a guess (a practice I learned from Dewar), but some of
the patches to gcc-2.7.2 distributed with gnat-3.09 break optimization
for the HPPA.

You haven't purchased support from ACT.

You can try gnat-3.10p, but some of my initial testing shows that the
patch file distributed with gnat-3.10p still suffers from broken
optimization on this architecture. If those patches are integrated in
gcc-2.8 (as the patch file claims), then perhaps optimization will be
better when it's finally released and a gnat based on it is made
available.
Otherwise, try all optimization options on each source file and use
the resulting binary that works best.
