Thanks for looking into it.  I configured --with-wide-int on
my bigendian 32-bit host and could not reproduce the problem.
My host is a Solaris 10 sparc (32-bit).  I tried with both
Sun C 5.12 SunOS_sparc 2011/11/16 (cc -xO4) and with
GCC 3.4.3 (csl-sol210-3_4-branch+sol_rpath) (gcc -O2).

Since you built --with-wide-int, can you please also try
compiling from scratch, with
"make CPPFLAGS=-DGC_LISP_OBJECT_ALIGNMENT=4"?
It could be that your compilers claim to be aligning 64-bit
integers on 8-byte boundaries, but are occasionally actually
aligning them on 4-byte boundaries.  This messes up conservative
garbage collection big-time and would explain your symptoms.
