Hi, I got a similar issue when trying to use LuaJIT with JNLua and the OS X 64 bits Java JVM... it also segfaults. Since I can't relink the JVM with the -pagezero_size flag I had to stick with Lua 5.

Umm, maybe the Valgrind binary itself can be relinked with the -pagezero_size flag? Either run the tests on a 32 bit binary or run the tests on Linux/x64 (where Valgrind works just fine). No chance.

Hi all, I'm trying to link LuaJIT into an application on 64-bit Mac OS X. Following the instructions on the LuaJIT website, I've added -pagezero_size 10000 to the linker flags; if I don't, I get a se

I have attached to this email the result of a Valgrind run with -O3 -O-fwd (works) and another one with -O3 only (does not work). As I said: better compile a 32 bit binary, since Valgrind isn't near

Hi list, At work we use Lua in an embedded environment. It's a large project that does a lot of network IO. After some profiling, I discovered that luaL_addlstring was consuming a large amount of the

Okay, so I've installed Linux+Valgrind but I can't compile LuaJIT in 32bit mode for it to use the system allocator because Ubuntu doesn't provide the debug-symbols-included version of glibc for 32bit

If you happen to be running on Linux, valgrind[1] sometimes helps to track down those kind of problems: valgrind --tool=memcheck <your-app> - Jeff [1] http://valgrind.org/

I just found an ugly valgrind-detect glitch... not 100% sure on how to diagnose this, but inlined is the output. It looks like either it was directly caused by the GC-ed coroutine: ==15379== Memcheck

Hi, None of these are errors. This is just copying uninitialized memory. Either without using it or by overwriting it later with valid data. Modern memory checkers do validity bit propagation. They s

Valgrind works fine here in 32 bit mode on Ubuntu/x64 10.04. But then I have a populated /usr/lib/debug/lib32/*, which came from libc6-dbg. Not sure this is the same for all Ubuntu releases. Yes. Ye

Large amounts of (non tail) recursion runs out of memory eventually. But not necessarily in the same place with Valgrind. Its not an issue. Justin
