Executable redefined ?

Hi,
I have generated a swi-pl executable from my C and prolog files.

Everything was working fine.

I executed a script that went wrong (don't know what, but well... this
is my problem to fix). My exe takes as argument a prlog script which it
loads and execute on a specific predicate.

Since this problem, all my runs fail (even the one that were fine before).

When I look at the logs, prolog says that a predicate does not exists
(and it did as it used to work).

I have to reinstall my whole application (rpm packaged, on a Fedora 19,
swipl 6.2.6, 64 bits) to get it worked again. It looks like a "context"
is saved somewhere... but where and how ?

My application do not explicitly do any "save" of the context.

I have no idea how to debug this.

Thanks

Olivier
