I just tried to compile the package geotiff-1.2.5-0.pm.1
with the GNU C++ compiler version 4.4 snapshot 20081205.

The compiler appears to get into a long or possibly infinite loop.

gcc -c -fstack-protector -Wall -fPIC -DCSV_DATA_DIR=\"/usr/share/epsg_csv\" -I.
-I.    ./geo_print.c./geo_print.c: In function 'GTIFImport':
./geo_print.c:492: warning: dereferencing pointer 'sptr' does break
strict-aliasing rules
./geo_print.c:481: note: initialized from here
./geo_print.c:481: note: initialized from here
./geo_print.c:481: note: initialized from here
./geo_print.c:481: note: initialized from here
./geo_print.c:481: note: initialized from here
./geo_print.c:481: note: initialized from here
./geo_print.c:481: note: initialized from here
./geo_print.c:481: note: initialized from here
./geo_print.c:481: note: initialized from here
./geo_print.c:481: note: initialized from here
./geo_print.c:481: note: initialized from here
./geo_print.c:481: note: initialized from here

and so on for at least 16 million lines.

Preprocessed source code attached. Flags -c -O2 -Wall required.
