Hi all,

I need to do some coordinate transformation with GDAL in a thread of my
application and with some set of spatial references the call
to OGRCreateCoordinateTransformation seems to stuck somewhere in the code.

It is true when trying to convert from WGS84 to +init=IGNF:LAMBE +wktext"
(or any srs from IGNF).

If I copy/paste the definition of the IGNF file instead of using the
preceding definition, the call works. Apparently, it's a problem with PROJ
which seems to have a problem with the access to the IGNF file.
