[Gdal-dev] MrSID Segmentation Fault

[Simpson]

Andrey,

Did you find the issue?

If not, below is another run of gdalinfo compiled with CFG=debug.

I am not adept with gdb, so let me know how/what other data would be
helpful.

Thanks again for your help,
Drew.



(gdb) run n_16_30_2000c.zu.sid

Your gdab output does not contain debug info. To build GDAL with
debugging information you should whether use the command

 $ CFG=debug make

or just export 'CFG=debug' environment variable in the shell profile.

Ok, it seems that I have found and fixed the problem.

Frank, could you post the new anonymous CVS access instructions for
GDAL?
