From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0.0) Gecko/20020623 Description of problem: After a successful build of glibc-2.2.5-37 binary RPM on an i586 system, running the glibc self-test suite causes a failure of the "tst-rndseek" test to complete successfully. Version-Release number of selected component (if applicable): glibc-2.2.5-37.src.rpm How reproducible: Always Steps to Reproduce: 1.Unpack glibc-2.2.5-37.src.rpm 2.Comment-out the running of the "make check" in the glibc.spec file 3.Run: rpm -bb /usr/src/redhat/SPECS/glibc.spec 4.Note successfull build of binary RPMs. 5.Go to /usr/src/redhat/BUILD/glibc/build-i386-linux and run "make check". 6.You see the GBxxxxx locale test fail (this happens of all platforms). Run "make check" again to resume self-test. No other errors seen. [The above is our baseline. Now on to the bug report.] 7.Run: rpm -bb --target i586-redhat-linux /usr/src/redhat/SPECS/glibc.spec 8.Again the build of the binary RPMs is OK. 9.Go to /usr/src/redhat/BUILD/glibc/build-i586-linux and run "make check". 10. As before, the GBxxxx locate test will fail. Restart again with "make check". 11.Now the self-test suite will stop on the failure of test "tst-rndseek". The reported error is that the test timed-out. Actual Results: Running the self-test shows the GBxxxx locale test to fail on i386, i586, and i686 system. It is only on i586 build, though, that the tst-rndseek test fails. Expected Results: Running the self test on an i586 build should not show any more errors than on any other platform. Additional info: 1. The i586 build was done on an i586 system. (The i386 and i686 builds referenced above were done on K6-III and i686 systems, respectively.) 2. The compiler used for the build was gcc-2.96-112, binutils were binutils-2.11.93.0.2-11. These tools were used on all builds referenced in this bug report. 3.If the self-test is not commented-out in the spec file, the error(s) are ignored and the build completes successfully. Certainly the GBxxxx failure occures and is ignored. I have not had the occasion to notice any other errors masked by the forgiving launch of the self-tests from the spec file.
As for the GBxxx failure, that's because in 7.3 glibc GB18030 iconv module was modified to follow Chinesse government request to handle even unassigned Unicode points but charmaps/GB18030 was not updated. You can check out latest rawhide glibc where the test works just fine. As for tst-rndseek, if it timed out, it most probably means just that the machine is too slow to run 10000 fseek+2xfgetc calls in less than 2 seconds. You can try to run the test by hand with --direct option to see if it actually finishes (elf/ld.so --library-path . stdio-common/tst-rndseek --direct).
