Funny, but I can't reproduce this one:

: $ gdb generic_slave 3977
: GNU gdb 6.1.1 [FreeBSD]
[snip]
: 0x280fe638 in ?? () from /usr/local/lib/gcc-4.2.0/libstdc++.so.6
: (gdb) bt
: #0  0x280fe638 in ?? () from /usr/local/lib/gcc-4.2.0/libstdc++.so.6
: #1  0x2816bceb in operator delete ()
:    from /usr/local/lib/gcc-4.2.0/libstdc++.so.6
: #2  0x08057059 in path::addmark ()
: #3  0x08051ce2 in cell::accelerate ()
: #4  0x0804c8c1 in simulation::simstep ()
: #5  0x0804aa30 in call_server ()
: #6  0x0804b1d5 in main ()

No debugging symbols here, but I've tried a simple program with them too
and everything still works:

: $ gdb c 4505
: GNU gdb 6.1.1 [FreeBSD]
[snip]
: main () at c.c:4
: 4               while (1);
: (gdb)

Detaching is also correct. Something is probably wrong/different in your
setup, it works OK here.

HTH,
