Running this code:

local Profiler = require('profiler')

function love.load()
    Profiler.start('profile.txt')
    love.math.random()
    Profiler.stop()
end

function love.update(dt)
    print('here')
end

Causes love to crash silently without ever printing "here".

Contents of profile.txt:

Code: Select all

stack_level     file_defined    function_name   line_defined    current_line    local_time      total_time
8       (string)        gsub    -1      1410    0.000035        0.000035

I compiled profiler from this code: https://github.com/luaforge/luaprofiler

With a small patch to get it to compile:

Anyone know why? I need to track down a perf bug in my game but the profiler is causing it to crash before getting any meaningful data.

Edit: Also tried with LUA_INCLUDE= /usr/include/luajit-2.0 (luajit 2.0.3-3) with the same results.

Edit 2: Oops, I'm an idiot, ignore me. I forgot that I fixed this bug in a fork of luaprofiler: https://github.com/clofresh/luaprofiler ... 39e14268f2

try just using math.random(max value)
Edit: Just read your edit xD
