Thanks for the report!  I committed a slightly different version in commit 80fc43f2cf12c7a21a0533cc84e91059ef9d8170.

After installing a debugging version of bdwgc, I tried installing
Guile from trunk.  After running autogen.sh and configure, I added

#define GC_DEBUG 1

to config.h

Running make resulted in

scm_c_get_internal_run_time tries to run get_internal_run_time before
get_internal_run_time has been initialized w/ a value (a pointer to a
function).  There is no crash after moving the scm_init_stime call in
init.c to run before the scm_init_posix call.  Further (standard,
non-debugging) builds of Guile trunk have also succeeded after moving
up the scm_init_stime call in init.c .
