Uncrustify Code Beautifier

I am getting indent or aligning issues on this block of code, after running uncrustify 0.53. Below is the original code segment, which I want to keep exactly as-is (note the braces).

{
int some_integer
#if defined(WIN32)
SYSTEMTIME st;
DWORD ThreadId;
#else
struct timeval mytv;
struct tm * mytm;
pid_t ProcessId;
#endif

#if SOME_COND
(void) loop;
#endif
}

uncrustify will always give me 1 extra indent on the last #if block, like below

#if EV_MULTIPLICITY
(void) loop;
#endif

But the extra indent does not kick in on any other line. Also, I ran the same config file on uncrustify .47 and I did not get this problem. Does anybody know if this is a bug, or simply a feature I missed in my config file?

Here's a list of rules from my config which are relevant,

input_tab_size=4
output_tab_size=4
string_escape_char=92
indent_columns=4
align_pp_define_span=0
pp_region_indent_code=false
pp_define_at_level=false
pp_indent_at_level=true
pp_indent_if=1
pp_indent=ignore
pp_if_indent_code=false
