Yes, a lot. However I can't see how it could crash.

The crash happens in glibc's fprintf. This one is called from a debugging macro
that is used all over the place,

    say(0, RPC2_DebugLevel, "RPC2_SendResponse()\n");

where say is defined as,

#define say(when, what, how...)\
    do { \
        if (when < what){ \
	    fprintf(rpc2_logfile, "[%s]%s: \"%s\", line %d:    ", \
		    rpc2_timestring(), LWP_Name(), __FILE__, __LINE__); \
	    fprintf(rpc2_logfile, ## how); \
	    fflush(rpc2_logfile); \
        } \
    } while(0);

The crash happens during the first fprintf call, and I don't know why.
rpc2_timestring() definitely returns a valid pointer, __FILE__ and __LINE__
should be good as well, so only the parameters coming from rpc2_logfile and
LWP_Name() could be suspicious.

What compiler / libc versions are you using?
