[postgis-devel] Pstgis raster ST_SetValues crashes server, or is it GDAL?

[Rémi Cura]

Hey List,
I encountered another annoying problem :
I can reproduce it 100%, but I failed to produce an isolated test case.

Problem occurs when using the ST_SetValues function to populate a freshly
created raster band. It works the first time, then crashes the server (see
stack, log only says : segfault)

Strange point is : It is a plpgsql I wrote wrapping st_setvalues that
crashes, and the same code doesn't crash outside a plpgsql function.

Somebody would have any idea about that?

Cheers,
Rémi-C
