DEC Ada on AXP: Program_Error in task terminations

[Mats.Weber@elca-matrix.ch (Mats Weber)]

Hi,

(I have already posted this question a few months ago, when Charlie and
other DEC Ada people were not reading this newsgroups. Maybe I'll be
luckier this time :-)

I get error messages like the following at the end of the execution of
tasks in programs that I run on VMS/AXP compiled with DEC Ada v3.2 or 3.3.
The program otherwise runs fine, the messages appear at the end of the
program's execution, and the main program terminates without exception.

The exact same program runs fine on VAX/VMS and UNIX (compiled with
Rational/Verdix VADS).

I have checked what "-LIB-F-BADBLOADR, bad block address" means: it can be
a block of memory that is deallocated twice or that kind of thing. I have
checked the program and I think it is free of that kind of error (I cannot
prove it, though).

Moreover, these errors are not systematic: some runs of the program do not
produce any error messages at all.

Has anybody else encountered the same problem ?
