Re: GUILE_MAX_HEAP_SIZE

Hi,

I just added `master' to the daily build on x86-64 [0] and it fails
there:

  lt-guile: gc.c:609: scm_i_gc: Assertion `scm_i_gc_sweep_stats.collected + 
scm_cells_allocated == scm_i_gc_sweep_stats.swept' failed.

I don't observe this failure on my x86 (Core(TM)2 Duo) laptop.

Thanks,
