GCC issue still here?

[Jean-Pierre Flori <jpflori at gmail dot com>]

Dear all,

I once again stumbled on issues reminding me of the ones mentioned here:
http://trac.sagemath.org/ticket/15366
and here on the cygwin ml:
http://cygwin.com/ml/cygwin/2013-08/msg00201.html
http://cygwin.com/ml/cygwin/2013-07/msg00528.html

Looking at the tickets on GCC tracker:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=57680
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=57982
and at the merged fix:
https://gcc.gnu.org/git/?p=gcc.git;a=blobdiff;f=libgcc/config/i386/cygming-crtbegin.c;h=53909d2dc145b59958193dd9486b8b5fe01e9246;hp=c34178787c85aa1b980c25beb455d5e9c41d4614;hb=024d645a0db64ac79bdb6cda0339a3d4d26e288b;hpb=0b67965817647f9b73762e147ea125566ee0659d
the fix looks slightly different, it does not deregister using the
suggested condition...

Would you say there still is a problem or should I look further into this?

Here is the backtrace I get with latest Cygwin GCC 4.9.2 when Python
exits and unregisters a lot of modules:
