Bug when instantiating long list of compounds from consulted file

[STREBELLE Alain]

Hello everyone,

I just came to this bug.

Assume that I have a prolog file "fatal_error.pl", which contains

a(

    [

      b(c),

      b(c),

      b(c),

      …

      b(c)

    ]

  ).

If I consult the file 

| ?- [fatal_error].

compiling /Dvlpt/trfmodels/fatal_error.pl for byte code...

/Dvlpt/trfmodels/fatal_error.pl compiled, 261 lines read - 26473 bytes written, 761 ms

(3 ms) yes

If there were less than 257 b(c) compound statements, I have no problem retrieving the knowledge:

| ?- a(R).

R = [b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c),b(c)]

Yes

If there are 257 b(c) compound statements or more, gprolog crashes:

Fatal Error: Segmentation Violation (bad address: 0x803)

The same happens in 1.4.0, in 1.4.4 and the latest unstable version from 20140207.

Thank for looking at this, and thank you for an otherwise very good product that saves my life every day.
