[clang] OpenOffice does not work with clang-compiled libgcc_s.so.1

2011-07-27 Thread Alexey Shuvaev 
Hello list!

I have decided that clang in mature enough to give it a try on a main
desktop. Everything is working fine except OpenOffice. The problem was
already reported [1] and even analyzed [2]. Although the OP has reported [3]
that since r218915 he has no problems anymore, I still have :(
Note, that according to [4] it seems it was not specifically fixed upstream.

So, if I compile the whole world (and kernel) with clang, soffice.bin
dumps core. If I recompile the world with gcc and replace /lib/libgcc_s.so.1
with the new one, OpenOffice works fine again. Here are some information
about the system that may be useful:

I don't have much time recently, so any further debugging will be on a
best effort basis. Anyway I thought it is better to post it here, so
it won't be just lost. If necessary I can file a PR about it.

Thanks,
Alexey.

Hmm, OpenOffice is a rather unwieldy testcase, not in the least because
it takes ages and many gigabytes to build. :(  Did you or anyone else
ever find a smaller testcase?

CCing office@, maintainers -- could be interested and may give answers.

FWIW, LibreOffice is probably a better target for clang -- seems to be
The Future.

By the way, I didn't mean that OOo is 'deprecated' at all; maho is
still working on it.

Hello,

I had a similar problem in the past, but IIRC after rebuild openoffice
it started to work again. The machine where it happened is not
available anymore.
