Re this:
(gdb) frame 2
#2 0x0100ffda in compact_small_strings () at alloc.c:2271
2271 abort ();
(gdb) info address from
Symbol "from" is multi-location:
Range 0x100f452-0x100f45c: a variable in $esi
What exactly the "range xxxx-yyyy" mean? There's nothing in the
manual about this format. Is that the range of PC values? If so,
then since the current frame address is not within those limits, it
seems, and therefore the information is not helpful.
Is there any way of knowing where will the variable be found for the
current PC value?
TIA

Most likely this means that if the current pc is outside of those
limits, the variable is not available anywhere.

Thanks. I will at least describe this output in the manual.
