That patch *did* fix a boatload of erro= rs on arm, but this segfault is an unrelated problem I think.  Only= happens on arm though.

Here is a way to reproduce:

In the= test-suite/standalone dir:
while GUILE_JIT_THRESHOLD=3D0 make TESTS= =3Dtest-language check-TESTS; do :;done

And then:
../../meta/u= ninstalled-env ../../libtool --mode=3Dexecute gdb ../../libguile/guile c= ore

Program terminated with signal SIGSEGV, Segmentation fault.#0  0x76f505cc in scm_is_string (x=3D0x0) at strings.h:293
293=        return SCM_HAS_TYP7 (x, scm_tc7_str= ing);
[Current thread is 1 (Thread 0x76fe6010 (LWP 21616))]
(gdb)= bt
