Re: Setting G_SLICE=always_malloc at runtime
Okay, I've figured out why g_slice_set_config wasn't working...at some
point g_quark_from_static_string was being called before
g_slice_set_config, hence the error.

Re: Setting G_SLICE=always_malloc at runtime
Do I set the environment variable? Because code like
setenv("G_SLICE", "always_malloc", 1);
g_thread_init(0);
doesn;t seem to work.
I noticed the g_slice_set_config functions in gslice.h and tried
g_slice_set_config(G_SLICE_CONFIG_ALWAYS_MALLOC, 1);
but this gives me the error
(process:6533): GLib-CRITICAL **: g_slice_set_config: assertion
`sys_page_size == 0' failed
and also does not work.
What am I doing wrong?

GSlice is initialized, i.e. it looks at G_SLICE, on the first use or when thread support is initialized. So just set the variable before that.
