[coyotos-dev] BigNum.cxx buglet?

[Jeroen Visser]

Just in case it helps, my make now errors out in

capidl -d -v -I. -D BUILD/h/idl -h -a i386 Range.idl

The segfault occurs at line 745 of BigNum.cxx because

(gdb) print thisDigit.getDigit(0)
$1 = 4294967295

Backtrace below.

-JCV


Program received signal SIGSEGV, Segmentation fault.
