If gdb receives an event on one thread while doing an eval of
a function on another then an error occurs as follows:
"
The program received a signal in another thread while
making a function call from GDB.
Evaluation of the expression containing the function 
(XXX) will be abandoned.\n\
When the function is done executing, GDB will silently stop.
"

I hacked this a bit seems like a very small 4 line addition in the resume
function in file infrun.c fixes the problem. heres a diff of the fix from
version 7.0

1284,1287d1283
<       else if(inferior_thread ()->in_infcall)
<         {
< 	  resume_ptid = inferior_ptid;
< 	}

I dont know what the impact other than it does seem to work and does not look
like it breaks anything. I would like to get this fixed and am willing to do it
if I get guidance as to how to test it and maybe on aspects I dont understand. I
tried to do it very locally but maybe it requires more effort.
Thanks,
Danny
