-fpic is broken. On Fedora 13, I got:
[hjl@gnu-15 gcc]$ ./xgcc -B./
/net/gnu-6/export/gnu/import/git/gcc/gcc/testsuite/g++.dg/torture/stackalign/eh-thiscall-1.C
-mstackrealign -mpreferred-stack-boundary=5 -O -c
[hjl@gnu-15 gcc]$ g++ eh-thiscall-1.o
[hjl@gnu-15 gcc]$ ./a.out
[hjl@gnu-15 gcc]$ ./xgcc -B./
/net/gnu-6/export/gnu/import/git/gcc/gcc/testsuite/g++.dg/torture/stackalign/eh-thiscall-1.C
-mstackrealign -mpreferred-stack-boundary=5 -O -c -fpic
[hjl@gnu-15 gcc]$ g++ eh-thiscall-1.o
[hjl@gnu-15 gcc]$ ./a.out
