sorry, took me a while, hope that will help you:

Breakpoint 1, gnustep_base_user_main (argc=1, argv=0xcfbc1a30) at 
NSView_autoresize_and_rounding.m:79
79              passed = CHECK(view1, NSMakeRect(10,10,110,10)) && passed;
Current language:  auto; currently minimal
(gdb) print view1
$1 = (class NSView *) 0x889f1e04
(gdb) print view1._autoresizingFrameError
$2 = {origin = {x = 0, y = 0}, size = {width = 0, height = 0}}
(gdb) c
Continuing.

Breakpoint 2, gnustep_base_user_main (argc=1, argv=0xcfbc1a30) at 
NSView_autoresize_and_rounding.m:81
81              passed = CHECK(view1, NSMakeRect(10,10,10,10)) && passed;
(gdb) print view1._autoresizingFrameError
$3 = {origin = {x = 0, y = 0}, size = {width = -0.999997139, height = 0}}
(gdb)
