With guile 2.2.4 (and guile 2.2.3 as well), I get a nasty segfault during build:

Running a bare "./meta/build-env guile" with no other options gives me
a similar segfault. Loading up the resulting core files in gdb reveal
that both crashes happen at the same point in libguile/vm-engine.c:

I dropped an fprintf(stderr,...) debug in that codepath to see what
address that code is attempting to unpack. guile and guild both
consistently hit that codepath twice and crash on the second one; both
pointer values appear to point to reasonably sane addresses:

Segmentation fault (core dumped)
FYI this is building for 32-bit SPARC, Linux 4.16.18, gcc-8.2.0,
glibc-2.28, gc-7.6.8, libatomic_ops-7.6.6 (gc and libatomic_ops both
pass all tests). CFLAGS/CXXFLAGS is currently set to "-g -O2
-fdebug-prefix-map=/usr/src/dist/guile-2.2.4/debian/tmp.build=.
-Wformat -Werror=format-security -m32 -mcpu=v9 -mtune=v9
-fno-stack-protector" (I have also tried with -O1, with similar
results). Building 64-bit guile on the same SPARC system (Sun
Enterprise T5240) exhibits no such crash.
Google dug up a few similar reports for 32-bit PowerPC, but apparently
nobody really took a close look at the time. Is this maybe a problem
specific to 32-bit big-endian architectures?
I can supply the corefiles and config.log on request. Be warned the
corefiles are about 260K compressed (122MB uncompressed).
