[gdal-dev] JP2 Segfault

[Yves Jacolin]

Tomaka,

I am using gdal with docker (https://hub.docker.com/r/homme/gdal/). I did not 
build gdal by myself even if I am able to do it but I have to use a docker 
container as we are in such infrastructure.

Anyway, using SDK 5.3 could be a solution if openjpeg lib is not fast enough.

Y.
