Crash report
Hi! This happens with Fedora 8 recently updated system also. Version of OpenOffice used : openoffice.org-core-2.3.0-6.11.fc8 Additional info : It seems only the characters 09F0 and 09B0 are affected. Others are rendered properly in the combination mentioned above. Sorry, it seems it is happening with other characters also. Just now I tested with 09F1, 09A6 and 09AA. It did crash with 09F1 and 09A6. hi! crash also occurs with the following combination types : 1. 09F0+09CB+0983 2. 09B0+09CB+0983 3. 09F0+09CB+0982 4. 09B)+09CB+0982 Seems like 0981, 0982 and 0983 are affected when combined with 09CB. Patched now logged at http://bugs.icu-project.org/trac/ticket/6213 icu built (building) for rawhide as icu-3.8.1-6.fc9 same bug is applicable for Tamil(ta_IN) and Malayalam(ml_IN) ta_IN 1. 0b95 0bcc 0b82 2. 0b95 0bcb 0b82 3. 0b95 0bca 0b82 ml_IN 0d15 0d4a 0d02 actually generelly speaking problem occurs when we input any "consonet+ split_vowel_matra + vowel_modifier", so total levels becomes 4 This is where it stands right now after my original fix, the third element, e.g. the 2-4 range below is the max worst-case-expansion. So e.g. tamil and malayalam are unchanged in my original fix. So I'm going to reset this to assigned for a bit to investigate if the tamil and malayalam ones need to be increased as well. It would be good if you could check the other categories of script below and see if there are cases for the other ones not covered here already that may need an increased expansion static const IndicClassTable devaClassTable = {0x0900, 0x0970, 2, DEVA_SCRIPT_FLAGS, devaCharClasses, NULL}; static const IndicClassTable bengClassTable = {0x0980, 0x09FA, 4, BENG_SCRIPT_FLAGS, bengCharClasses, bengSplitTable}; static const IndicClassTable punjClassTable = {0x0A00, 0x0A74, 2, PUNJ_SCRIPT_FLAGS, punjCharClasses, NULL}; static const IndicClassTable gujrClassTable = {0x0A80, 0x0AEF, 2, GUJR_SCRIPT_FLAGS, gujrCharClasses, NULL}; static const IndicClassTable oryaClassTable = {0x0B00, 0x0B71, 3, ORYA_SCRIPT_FLAGS, oryaCharClasses, oryaSplitTable}; static const IndicClassTable tamlClassTable = {0x0B80, 0x0BF2, 3, TAML_SCRIPT_FLAGS, tamlCharClasses, tamlSplitTable}; static const IndicClassTable teluClassTable = {0x0C00, 0x0C6F, 3, TELU_SCRIPT_FLAGS, teluCharClasses, teluSplitTable}; static const IndicClassTable kndaClassTable = {0x0C80, 0x0CEF, 4, KNDA_SCRIPT_FLAGS, kndaCharClasses, kndaSplitTable}; static const IndicClassTable mlymClassTable = {0x0D00, 0x0D6F, 3, MLYM_SCRIPT_FLAGS, mlymCharClasses, mlymSplitTable}; static const IndicClassTable sinhClassTable = {0x0D80, 0x0DF4, 4, SINH_SCRIPT_FLAGS, sinhCharClasses, sinhSplitTable}; pravin, for assamese (and hopefully bengali also), it happens only with consonant+09CB+{0981,0982,0983}. i have tested it on my Fedora 8 box that other vowel_matra and {0981,0982,0983} combination doesn't break. don't know if this helps caolan in his work, but i just wanted to mention what i found. caolan, i have the diff file you have mentioned earlier..how do i apply the patch and test it on my rawhide box ? can you generate the same diff for Fedora 8 also ? (In reply to comment #8) > pravin, > for assamese (and hopefully bengali also), it happens only with > consonant+09CB+{0981,0982,0983}. Just tested for Bengali, consonant+09CC+{0981,0982,0983} breaks as well. hth same for assamese also. so the problem exists with consonant + {09CB,09CC} + {0981,0982,0983}. So the expansion of bengali/assamese, tamil and malayalam has been modified from 3 to 4, and http://bugs.icu-project.org/trac/ticket/6213 has been updated with those expansions. So those scripts are known and hopefully out of the way. The open question is if the other remaining "3" ones should also be 4, e.g. Oriya and Telegu, is there known similar constructs that have a parallel in those languages ? http://koji.fedoraproject.org/packages/icu/3.8.1/7.fc9/ for rawhide and http://koji.fedoraproject.org/packages/icu/3.8/6.fc8/ for F-8 to ease testing just tested in my Fedora 8. no crash as of now. i have tested for other script, where it is applicable it can be for tamil, oriya, and malayalam but it is crashing only for tamil and malayalam in rawhide as i said for oriya it working fine Wrt comment #6 For Rawhide using icu-3.8.1-7.fc9.i386.rpm ta_IN 1. 0b95 0bcc 0b82 (OO doesn't break for this combination) 2. 0b95 0bcb 0b82 (OO breaks) 3. 0b95 0bca 0b82 (OO breaks) ml_IN 0d15 0d4a 0d02 (OO breaks) Hmm, wrt comment #16, are you sure you have the fixed libs ? What is the output of > rpm -qf /usr/lib/libicule.so.38.1 i.e. it should be... libicu-3.8.1-7.fc9.i386 which passes the above test for me without crash and burn done...no crash (libs fixed) icu-3.8-6.fc8 has been submitted as an update for Fedora 8 icu-3.8-6.fc8 has been pushed to the Fedora 8 testing repository.
