[basile at starynkevitch dot net]

the preprocessed file, which I uploaded on 
http://starynkevitch.net/Basile/jaksy-g++-4.1.0-20050717-bug.ii.gz (md5sum of
gzipped file is e71436c0b8f93cef110aa6068b13bcb3) produce a reproducible
compiler bug:
 /usr/local/bin/g++_4_snap -c jaksy.ii
jaksy.hh: In constructor 'Jaksy_TVector<ctag, ScalarT,
VectorT>::add_first(VectorT*, ScalarT)::QishCpp_Locals::QishCpp_Locals() [with
int ctag = 1007, ScalarT = void*, VectorT = Jaksy_Vector]':
jaksy.hh:672:   instantiated from 'static Jaksy_TVector<ctag, ScalarT, VectorT>*
Jaksy_TVector<ctag, ScalarT, VectorT>::add_first(VectorT*, ScalarT) [with int
ctag = 1007, ScalarT = void*, VectorT = Jaksy_Vector]'
jaksy.hh:734:   instantiated from here
jaksy.hh:672: internal compiler error: in tsubst_copy, at cp/pt.c:7684
Please submit a full bug report,

This bug is the same with g++-4.0 from debian/sid and with latest CVS (from
yesterday) of gcc.

(this is from a free GPL/LPGL software I am currently developping. The program
may be not very meaningful yet; it is experimental).

Created an attachment (id=9293)
 --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=9293&action=view)
preprocessor output (gnuzipped) of failing code

Sample code (preprocessor output with g++ -C -E and appropriate -I) which
demonstrate thje bug. Sorry, I've got no smaller case. But I guess the problem
lies within the Jaksy_TVector template, which is not that big. Most of the
includes come from Qt4 (not very used) and my Qish garbage collector (see
http://starynkevitch.net/Basile/qishintro.html for more, get its latest
snapshot).

The attachement is self-contained and does not need any other file.

I tried several other ways of coding, and the same bug appears.

Regards.

This code is invalid.  You cannot access a local variable in a local class.
