Without knowing what compiler version you are using, there is nothing
more I can do here.
There are 34 calls to bigrecy() in scl.c and subr.c. You could comment
out half of those calls and see if it fixes the problem; then comment
out only 1/4 of the calls, and so forth until you isolate the call or
calls responsible for the error.
