Yes, it helped, the max start-process number is improved from ~30 to
~37. I think it's hit another issue.
Here's the details:
I can't run rebase.exe on cygwin1.dll directly, since the latter is
loaded by the former. I wrote a .bat file to rebase it:
cd c:\cygwin\bin
c:
copy cygwin1.dll 2.dll
rebase -b 0x45000000 2.dll
copy 2.dll cygwin1.dll
I did not try to rebase cygwin1.dll to the end of all other DLLs though,
I don't know if that is feasible. Instead, I just make it a lot more far
away from the DLL that's next to it in the address space.
(The old base for cygwin1 is 0x61000000, and next is cygncurses-9.dll
based at 0x61650000, the max cygheap is ~6.6M; new cygwin1 base is
0x45000000, and the next DLL is cygz.dll, with a base 0x54950000, with a
max cygheap ~256M).
After this, the emacs can start more processes, but still not unlimited,
neither will it segfault; it just exits will code 255 after printing
"Wrong type argument: stringp, 0". This must be another issue now, I
will debug it when I have more time.
$/bin/emacs --batch -q --execute '(let ((num 0))
(while (< num 80)
(setq num (+ num 1))
(message "num is %d" num)
(start-process "hello" nil "/usr/bin/echo")))'
---------------- output ----------------
...
...
num is 37
Wrong type argument: stringp, 0
