Autotest: framework/optional/f_help_topics.bas

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.
Comment 7 mikhail.voytenko 2009-10-14 08:20:29 UTC 
The fix is commited in fwk123.

Looks good on Solaris x86, setting verified.

Good in m3, closing
