egcs-1.1a - template bug

[Ryszard Kabatek]

There is a serious template bug in egcs-1.1a 
(not in egcs-1.0.2 or gcc-2.8.1).

My configuration:
Linux (RedHat 5.1), Pentium II
binutils-2.9.1.0.4-2
gcc version egcs-2.91.57 19980901 (egcs-1.1 release)


The first sample (sample1.cc) with a vector as member does compile well.

The second (sample2.cc) with inheritance from std::vector causes an
internal compiler error:
g++ sample2.cc

sample2.cc: In method `vectorN<double,100>::vectorN<double, 100>(unsigned
int = N, const double & = T())':
sample2.cc:12:   instantiated from here
sample2.cc:8: Internal compiler error.
sample2.cc:8: Please submit a full bug report to `egcs-bugs@cygnus.com'.

The third sample (sample3.cc), with inheritance from std::vector and
a template defualt parameter:

g++ sample3.cc
The only way to end the compilation was ^C.
No message.
