Re: Strange bug in irb1.9
Peter, this is bug in your code, not ext lib or ruby-1.9
Actually, your problem is that in your code (rconfig.c) you create
some intermediate objects that *can* be garbage collected in IRB
session (and *will be* under some conditions, as crash.rb shows):
---8<----
aConfigScalars =3D rb_ary_new3(5, cConfigFixnum, cConfigBignum,
cConfigFloat, cConfigBoolean, cConfigString);
aConfigAggregates =3D rb_ary_new3(3, cConfigGroup, cConfigArray, cConfigL=
ist);
aConfigSettings =3D rb_ary_plus(aConfigScalars, aConfigAggregates);
---8<---
as these values are never references from other objects, they die in
GC, receive junk data, and lead to crash:

usually, in 1.8.x C extensions people overcome this by declaring
global variables, or constants under class (there might be other
options, like freezing, or pure-c managing of consts, but
aforementioned two are most common)

rconfig_do_append(new_setting, rb_hash_aref(hash, key), key);
}
}

2) just curious, why C extension, and not FFI, as you use quite a
bunch of Ruby methods and few libconfig structs/calls? (see
