Issue #72 describes the same problem. I have just done some tests and compared between gsc from the installer and HomeBrew
Ok here is the error message :
The full verbose (gsc -verbose test.scm)Parsing:  fact-aux  fact

Here is the code:;(standard-bindings) (extended-bindings) (block))(define (fact-aux n a)  (if (<= n 1)      a      (fact-aux (- n 1) (* a n))))
(define (fact n)  (fact-aux n 1))
**************************************************Then I reinstalled the HomeBrew gambit and I got this :
Parsing:  fact-aux  fact

***************************************************
To my surprise the HomeBrew gsc uses clang and not the gcc-4.2 though it was given the path at installation.
Same gambit versions but different command lines !!!!!
-fschedule-insns2 seems to be one part of the problem
Thanks,
Denis

I finally installed apple's old gcc4.2 and then gambit with HomeBrew (the gambit formula allows to specify a compiler) and it seems to work fine. Well I might get some problems when linking with some 10.9 libs, I have no idea whether apple's previous and present compilers produce compatible binaries or not.
