Description joerg.skottke 2009-09-30 11:52:09 UTC
Autotest: framework/optional/f_help_topics.bas Reproduction - Open help - Select Index tab - Select Writer application - Search for "data" - display topic - move down one topic (cursor) - display topic Repeat last two steps until application crashes.
Comment 1 joerg.skottke 2009-09-30 12:05:02 UTC
Please use Solaris x86 to reproduce, it appears that just displaying enough topics causes the help viewer to crash at some point. Stacks have been submitted but are not yet available
Comment 2 joerg.skottke 2009-09-30 12:46:54 UTC
Stack-ID is: r4hrrdc
Comment 3 joerg.skottke 2009-09-30 12:50:01 UTC
Crash -> P2
Comment 4 joerg.skottke 2009-09-30 12:53:57 UTC
Last 100% good build was m48, following builds had warnings (up to m57 which was the last time cat3 tests where executed).
Comment 5 ab 2009-09-30 13:24:22 UTC
ab->mav: Stack shows no xmlhelp related entries. Please have a look if help viewer code is involved.
Comment 6 mikhail.voytenko 2009-10-14 07:29:46 UTC
The main reason for the crash was memory corruption. There were three problems that have affected the scenario and could cause the memory corruption: - sal IO implementation had no mutex, it was not necessary before, but buffered IO needs mutex to be thread safe - xmlhelp implementation has used pointer to array that has been deleted already - package implementation had no mutex on stream creation The first and the third problems are related to multithreading, since the images are loaded in different thread for html pages ( help uses html filter ). The fixes are ready, I will look for cws.
