Bug#554574: libstdc++6: apt segfaults on hppa

[Domenico Andreoli <cavok@debian.org>]

Package: libstdc++6
Version: 4.4.2-2
Severity: grave

Hi,

  after this morning upgrade apt started to systematically segfault
on my hppa box, not even an update was allowed. i reported this on the
hppa porters list [0].

of course suspect no. 1 is the NPTL switch but downgrading eglibc to
2.10.1-3 or even -2 did not improve the situation. i also tried with
standard kernel 2.6.30-2-parisc-smp (at that moment i was running
2.6.32-rc5) but still nothing.

then i tried to rebuild apt with the latest stuff, just in case NPTL
switch introduced any compatibility issue but g++ died at least one
time during usual autoconf g++ usability tests.

finally i tried downgrading libstdc++6 to 4.4.2-1 and it looks like
the problem is gone. indeed this package was upgraded this morning.

in the meanwhile 2.6.32-rc6 had been built and booted nicely. i've
then been able to use apt again and re-upgraded eglibc to 2.10.1-5 and
everything still works.

upgrading g++-4.4 & related stuff back to 4.4.2-2 not only reintroduces
the problem but it does not even get past the whole process dying before
the end. downgrading to 4.4.2-1 settles everything again.

frankly i do not know what to do next, besides trying to rebuild gcc-4.4
4.4.2-1 with latest eglibc to see if it is the culprit or it is rather
the svn merge between gcc 4.4.2-1 and -2.

thanks,
Domenico
