Re: Setting G_SLICE=always_malloc at runtime

["Raja Mukherji" <rajamukherji gmail com>]

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?
