msh3 extract run out of memory

[sgarnotel]

The extract function of the msh3 library run out of memory (128G RAM machine) on this example:
ExtractExample.txt
(the file extension is .txt due to Github limitations, it is an .edp file)

The error occurs in msh3.cpp - line 5952

Is it due to a mesh misdefinition or to the FQuadTree function ?

Je ne sais pas ce que fait cette fonction .

This function extract a mesh part using the region number.
In msh3.cpp, the C++ function cut the original mesh pTh in pThnew and build a FQuadTree (what this type means for?) using the pTh object to build it.
Should FQuadTree use pThnew object instead?
