Getting there ... maybe ..

In m_signals.c find this

	 if (event != NULL) {
	    if (haveaddr)
	       VG_(message)(Vg_UserMsg, " %s at address %p", 
			    event, info->VKI_SIGINFO_si_addr);

which is around line 1280 in the trunk sources.  I need to know
the value of *(UInt*)(info->VKI_SIGINFO_si_addr) when the message
is printed, iow change to

	       VG_(message)(Vg_UserMsg, " %s at address %p insn=0x%x", 
			    event, info->VKI_SIGINFO_si_addr,
                            *(UInt*)(info->VKI_SIGINFO_si_addr)
                            );

We could also (possibly) short-circuit all this: does your cpu have
some limitation on FP instruction support?  I ask because I think it
is barfing on the code that Valgrind generates for itself to run.
