Problem compiling with g++/libc6




Can someone figure this out? The most trivial C++ program
crashes. (  main(){} )

The link between the compiler and libc6 seems fishy.
I have a slink system, with both libstdc++2.8 and
libstdc++2.9.

------
wintermute:test >g++ --version 
egcs-2.90.27 980315 (egcs-1.0.2 release)

wintermute:test >cat /etc/debian_version 
2.1

wintermute:test >cat a.cc
main()
{
}

wintermute:test >g++ -o a a.cc
wintermute:test >a
Segmentation fault
wintermute:test >ldd a
        libm.so.6 => /lib/libm.so.6 (0x4000b000)
        libc.so.6 => /lib/libc.so.6 (0x40024000)
        ld-linux.so.2 => /lib/ld-linux.so.2 (0x400c9000)
----------

The debugger points at libc6:


wintermute:test >gdb a.out

0x400d291f in ?? () from /lib/libc.so.6

But, this works:

wintermute:test >egcc --version 
egcs-2.91.60 
wintermute:test>egcc -o a a.cc 
wintermute:test >a
wintermute:test >ldd a
        libc.so.6 => /lib/libc.so.6 (0x40010000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)


Any (non-null :-) pointers appreciated.
