Description of problem: I just tried to compile package tetex-3.0-4 from Redhat Fedora Core development tree with the gcc 4.0.0 compiler and the compiler flag -Wall. The compiler said 1. aleph1.c:5346: warning: 'alpha' is used uninitialized in this function The source code is fonttables [f ][ k ].cint = sw - alpha ; I agree with the compiler. Suggest initialise local variable "alpha" before first use. 2. omega1.c:3616: warning: 'alpha' is used uninitialized in this function omega1.c:3611: warning: 'beta' is used uninitialized in this function aleph1.c:5341: warning: 'beta' is used uninitialized in this function Duplicates. Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info:
aleph1.c and omega1.c are generated during compilation. Because this seems not to be severe as there are no known bugs as the cause of this, closing WONTFIX.
>aleph1.c and omega1.c are generated during compilation. Time to look at the source code of the files they are generated from ? >closing WONTFIX. Code which is known to read random data is just asking for lots of downstream trouble, surely ? I've seen lots of projects which do a lot of downstream firefighting, but they never seem to look at upstream, which is where a lot of the downstream firefighting can be avoided.
Right, any use of uninitialized variable is bad and may case problems downstream. The code that generates these files need to modify/add the algorithm of its generation what's better to be reported upstream. I'm subscribed to upstream teTeX mailing lists and I see Thomas Esser replies quickly to user requests there. I did several posts there as well and have this experience. The most of things discussed there are mostly related to problems on a particular architecture or usage related problems. IIRC I haven't noticed an email about usage of uninitilized variables yet. You may want to report this problem there to make upstream developers aware of this problem. To post a report you can use tetex@dbs.uni-hannover.de or visit http://www.tug.org/tetex/ to see all upstream mailing lists. Me or you may close this bug UPSTREAM when the problem is reported there.
Closed due to user inactivity.
