I hope I filed this bug in the correct category, but Your 'components' don't make any sense to me. Your manual doesn't state which component GList is part of.

Anyways...

Using this snippet of code:

void blah() {
	static int j = 0;
	printf( "call no. %i\n", ++ j );

	GList* abc = NULL;

	for( int i = 0; i < 100; i ++ ) {
		printf( "---> step %i\n", i + 1 );
		abc = g_list_append( abc, GINT_TO_POINTER( i ) );
	}

	g_list_free( abc );
}

int main() {
	while( 1 ) blah();
}

causes a segementation fault in call no. 1 step 48. The debugger says, g_slice_alloc causes it. Version is from ubuntu repository.
