[Valgrind-users] Memcheck with Jikes RVM

[Karl C. <ka...@cs...>]

Hello,

I am trying to get memcheck (valgrind-3.10.0.SVN) to run Jikes RVM (3.1.3+hg)
on an x86_64-linux machine in 32-bit mode. However when I run:

WRAP="valgrind --smc-check=all --undef-value-errors=no --workaround-gcc296-bugs=yes"
rvm -wrap "$WRAP" -X:gc:eagerMmapSpaces=true HelloWorld

I get a SIGSEGV in memcheck:

Looking at /proc/PID/maps shows that the faulting address (0x80000105) is not
mapped, and is located right above the RVM's heap (which I hard coded to end
at 0x80000000):

Any idea as to what's going on, or how I might debug the problem further?
Any Valgrind flags or options I might be missing? The RVM runs fine
on its' own, as well as in Nulgrind (and cachegrind and callgrind):

Also, when I turn back on undef-value-errors in memcheck, it reports an
