[raster] segfault on make check

[strk]

as of r7341, on a 64bit with gdal 1.9.0:

This look like it's failing on the transform too -- ah we have a Linux victim suffering the same pains as a windows person :).

I'll double check on my end - but I think this is a dupe #925.

On windows under mingw, I believe I get the same error followed by can't load libproj-0.dll.

Strk -- to confirm -- can you look at that ticket and try the regress for transform on your linux box and confirm you are getting the wrong answers?

[pracine]

I get the exact same message on Windows.

[robe]

okay I have marked this as dupe of 925

Which revision of GDAL trunk are you using? I'm using r22520.

[Bborie Park]

On r7363 on a 64-bit linux box, I can't replicate that error with testapi.

[strk]

Still fails here as of r7366. GDAL is 22149.

[Bborie Park]

Are you getting the same error message "padfSrcNoDataReal set, but padfSrcNoDataImag not set."?

[strk]

Nope, indeed that's gone. I'm just left with the segfault. Valgrind report attached (seem to reveal a few errors).

[Bborie Park]

Thanks for the valgrind. That is confirming what I'm seeing. I think I'm prematurely attempting to free memory.

Can you try r7367?

[Bborie Park]

Your posting a valgrind report got me moving to fix my glaring memory leaks in rt_api.c and testapi.c. I'll get along with valgrinding the full regression suite next.

[Bborie Park]

strk, can you see if you still experience the seg fault? If you don't, please close this ticket. Thanks!

[strk]

Still fails as of r7397

Can you try again with r7399? It seems that someone else has had similar issues according to the discussion:

r7399 works here.
