Well I made a small test program using my ordinary compilation options
(-g -O2 -gnato -fstack-check) and it happily allocated and used 300 MB
of heap, as I asked it to, so it seems that this is not a heap problem.
Sorry for a mistaken hypothesis, I should have checked it before posting
my question. But the problem remains and any advice will be gratefully
received, although I now suspect that the cause may be a programming
error, a Heisenbug that disappears in the debugger and does not manifest
on Linux for some reason.
