I have done several tries.

With STATIC_HEAP_SIZE 30MB (30*1024*1024) at the end of the build I find:

$ find /tmp/ -name "*stackdump*"
/tmp/emacs/lisp/international/temacs.exe.stackdump

Instead trying 32 MB seems to avoid the stackdump and STATIC_HEAP_SIZE 
should be >= 32 MB.

I have tried this:

gdb /tmp/build/src/temacs
(gdb)run --batch --load loadup bootstrap
[...]
(gdb) call report_sheap_usage(0)
Static heap usage: 12486816 of 12582912 bytes

But from the result it seems that I have not completely understood how 
this test should be executed! Sorry!
