<http://wiki.services.openoffice.org/wiki/Non_Product_Build> tells me
that an assertion failure is considered to be a bug and should be
reported. However, I had three different assertion failures within
the first few minutes using the program. So, I suspect that the
messages may be a result of my own misundertanding rather than a
problem in the code itself.
Unfortunately running a non-pro OOo results in many assertions popping
up. I was just recently frustrated by that once again, and decided (for
myself, at least) we should finally address that problem by letting
those assertions abort, so just now filed
<http://www.openoffice.org/issues/show_bug.cgi?id=109142>.
And, the prevalent notion that those assertions are not fixed, anyway,
has let many to no longer bother about them, especially not filing
issues for them. This would change when assertions abort, so that P1
reports would be filed (and fixed!) for them.
Let me pick on the first assertion which failed, and one which is
failing quite regularly. It is ...
Error: seekEntry(): Bad map
From File /home/terry/OOo_hacking/DEV300_m71/svl/source/misc/inettype.cxx
at line 818
( It looks to me like the code is testing for pointer values
increasing in successive array elements where it should be testing for
increasing values of the pointed-to strings. The pointers are
initialized from string literals at line 487 of the same file. So, it
is not too surprising that the assertion fails. )
This one is funny. (And, it appears, I'm free to laugh about it, as I
most probably wrote that code myself, what feels like ages ago...) The
DBG_ASSERT that obviously is intended to compare successive strings for
lexicographic sorting indeed just checks the string pointers for "<".
However, the way compilers work, the strings in the MediaTypeEntry
arrays are indeed likely allocated to increasing memory addresses, so
the (nonsensical) test would often actually succeed. Only if the
compiler is aggressive enough to merge string literals things will start
to break. Now addressed by
<http://www.openoffice.org/issues/show_bug.cgi?id=109146>.
Thanks for pointing it out!
