Description Milos Jakubicek 2009-04-22 20:39:41 UTC

Description of problem:

As Fedora packages are compiled with -O2, libgeotiff prints during the build following warnings which may cause unpredictable behaviour:

./geo_new.c:242: warning: dereferencing type-punned pointer will break strict-aliasing rules
./geo_print.c:492: warning: dereferencing pointer 'sptr' does break strict-aliasing rules
./geo_write.c:135: warning: dereferencing type-punned pointer will break strict-aliasing rules

For more information about this problem, read e. g. http://www.ethereal.com/lists/ethereal-dev/200309/msg00342.html.

Version-Release number of selected component (if applicable):

libgeotiff-1.2.5-4.fc11

- however i propose upstream a solution to get rid of warns.
