Re: Bison 3.0.3 (stable)

[Thomas Jahns]

Hello,

I've encountered some bugs when running the bison 3.0.3 tests/testsuite on AIX 
6.1 with xlc/xlC 11.1.0.17 and building for the 64bit API.

Please see the archive of log and failed directories at

<https://cloud.dkrz.de/v1/dkrz_52d098b8-a94b-444e-a318-f7b072f8e0d4/bug-reports/20150116bison-3.0.3-testsuite.tar.xz?temp_url_sig=c448096487a5e4bc96631d616b0716850a86fdd8&temp_url_expires=1422021482>

The link is valid till Friday. But I can provide a renewed one easily.

So far I've looked into some of the bugs, and most seem unrelated to bison 
itself, but rather specific problems in the testsuite:

095: triggers some internal error in xlC, unfortunately our service contract 
expired last year. I assume the specific problem could be tested for and the 
test skipped then.

189: the error output from xlC should probably be normalized in 
AT_SYNCLINES_COMPILE

241, 440-443, 463, 464 these can possibly be cured by choosing another language 
level with compiler option -qlanglvl=, but there's so many to choose from. Is 
the version of C++ bison would like documented somewhere?

426  427  428  429  430  431 432: looks like repetitions of basically the same 
bug.

Regards, Thomas
