Hi Dongsheng,
I don't see any occurrences of NULL in fpu-ia32.cc.
Perhaps this is a bug in the <csetjmp> or related header file
in your system?
And I'm doubt the assumption GMP does not support exception when cross
compiling:
$ git diff m4/ac_check_gmp.m4
diff --git a/m4/ac_check_gmp.m4 b/m4/ac_check_gmp.m4

How does this affect you? I mean, that setting only affects
the PPL testsuite and if you are cross-compiling you are
not using it.
All the best,
Roberto
