"Unknown error" during allocation

Question

Hello!
Has anybody got the same error?
Dim Source Basis
A AB AB Description
a2 -800 -1000 Unknown error (11/3) (11)
Here is the script which produce this error:
oknullstatus=YES;
naskip=YES;
naskip2=YES;
define a dimension text;
mnt a add 'a2' 'a21' 'a22' 'a23' 'a24' 'a25' 'a26' 'a27' 'a28' 'a29';
define arel relation a <a>;
arel(a'a21')='a2';
arel(a'a22')='a2';
arel(a'a23')='a2';
arel(a'a24')='a2';
arel(a'a25')='a2';
arel(a'a26')='a2';
arel(a'a27')='a2';
arel(a'a28')='a2';
arel(a'a29')='a2';
lmt a to all;
define avls valueset a;
define b dimension text;
mnt b add 'b1';
define ab variable decimal <a b>;
define aallmap aggmap;
allocmap joinlines ('relation arel operator heven args protect avls' 'end');
ab(a'a2')=-1000;
lmt avls to 'a21' 'a22';
ab(a'a21')=-100;
ab(a'a22')=-100;
allocate ab using aallmap;
I discovered that the problem occured when i want to allocate from a negative number! But in the real world (in my country) costs are usually represented by negative numbers, so this problem is serious!
Thanks for the quick reply!

I'm not sure why you're getting "Unknown error" - you should be seeing this:
a2 -800 -1000 A source was OVER ALLOCATED to its children (11)
But that's still a bug - negative numbers and PROTECT (and probably any modifier which causes ALLOCATE to need to renormalize data like MIN/MAX/FLOOR/CEILING as well) seem to interact poorly. It will be fixed in future patch releases, if you'd like a backport please file a TAR.
Thanks a lot for the concise test case, that really eases the bug hunting.
