[Rd] Conditional jump or move depends on uninitialised value(s)

Hi,
I'm using valgrind to check over some C/C++ code for an R library. I'm
getting the report (see below), but can't track down the uninitialised
value(s). I tried using --track-origins=yes in valgrind which gives:
==28258== Uninitialised value was created by a stack allocation
==28258== at 0xEE33D98: ??? (in /usr/lib64/R/lib/libRlapack.so)
I presume the problem is an uninitialised value being used in my code,
rather than in libRlapack, but there is a better way of tracking down
where it is?
Cheers,
Jarrod
