commit 4e0b5360aebcaff9e9659ed7243ca5ace2ea219a
Author: Ben Pfaff <address@hidden>
Date:   Mon Aug 20 00:00:33 2012 -0700

    sys-file-reader: Fix setjmp() technicality.
    
    The C standards say that the compiler is allowed to optimize away
    changes to local variables within a function between a call to
    setjmp() and a later call to longjmp(), unless the local variables
    are volatile-qualified.
    
    The 'info' local variable in sfm_open_reader() fits this
    description but wasn't volatile-qualified.  This commit fixes that,
    even though my compiler didn't in fact seem to have a problem with
    the previous version.

commit 4d4d8b75297c30d7c95c2ab753f2c4493ae221ee
Author: Ben Pfaff <address@hidden>

    sys-file-reader: Fix memory leak.
    
    The C standards say that the compiler is allowed to optimize away
    changes to local variables within a function between a call to
    setjmp() and a later call to longjmp(), unless the local variables
    are volatile-qualified.
    
    The 'dict' local variable in sfm_open_reader() fits this
    description but wasn't volatile-qualified.  GCC in fact optimized
    out the changes on my system, and this commit fixes that.
