invalid access to memory location

[robe]

This may be a duplicate of #2476 and could even be a windows 64 specific issue. I'm not tagging it as raster this time though cause I'm not sure its raster.

Leo has managed to trigger this error:

invalid access to memory location

To be a bit annoying. One is a nightly process he runs which he was able to get around the issue by changing the order of the steps in his process. The only thing odd about his process is his unorthodox use of PostGIS (converting times to geometries so he could use geometry intersection and aggregate functions).

The other was just geocoding some data.

Neither invoived using any raster functions. I haven't quite pinpointed what could be the issue, but he's managed to trigger the problem on two separate Windows 64-bit boxes (one running Windows 2012 R2 and another Windows 2008 R2)

But same version of PostgreSQL / PostGIS:

POSTGIS="2.1.3 r12547" GEOS="3.4.2-CAPI-1.8.2 r3924" PROJ="Rel. 4.8.0, 6 March 2012" GDAL="GDAL 1.10.0, released 2013/04/24" LIBXML="2.7.8" LIBJSON="UNKNOWN" RASTER PostgreSQL 9.3.5, compiled by Visual C++ build 1600, 64-bit

I think upgrading my build chain to gcc 4.8.3 might have fixed the issue. I shipped PostgreSQL 9.3 and 9.4 (PostGIS 2.1.5 with newer gcc build) and the job in question haven't been failing since we upgraded.

Leaving it open until further investigation.
