Is that in relation to bootstrap flags?  There's no PIC flags in the original
report.

The breakage is rather curious.  Build-with-CXX should not cause code
generation differences.  Can you please build normally-bootstrapped compiler
from the same source, build the testcase with the two compilers appending
-fdump-tree-all -fdump-rtl-all and attach the two series of dumps?
