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

--------------
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.
