I too was suffering from this problem, which started when I installed an additional 1gb of memory http://superuser.com/questions/496777/cygwin-runtime-errors-couldnt-allocate-cygwin-heap in my laptop. Many "external" commands failed frequently, "make" rarely worked reliably, even "ls -rtl" occasionally stopped. I tried the "change the heap chunk size" following the recommended microsoft fix and had this had no win32 error change. I was seeing this (I've copied it in to make this solution easier to search for) : C:\cygwin\bin\make.exe (24556): *** couldn't allocate cygwin heap, Win32 error 487, base 0x480000, top 0x48E000, reserve_size 57344, allocsize 57344, page_const 4096 84 [main] make 9072 fork_parent: child 24556 died waiting for longjmp before initialization make: vfork: No such file or directory I was reading about "setup" this morning (looking for a way couldn t allocate to store the proxy name and password - which, btw, I still haven't found a solution to) when I reached this page: http://www.cygwin.com/cygwin-ug-net/setup-maxmem.html I tried it and, while 1024 didn't work for me, 2048 did! I did this: regtool -i set /HKLM/Software/Cygnus\ Solutions/Cygwin/heap_chunk_in_mb 2048 And not a single failure since. If I change it back to 1024 or delete it, I get the problem back. You have to restart bash etc...to pick this up. I hope this helps. Jerry Norbury Norbury Consulting b.v. Amsterdam Erick Hagstrom wrote: Hello all. I've seen quite a few messages in the archives along these lines but have been unable to make the problem stop. I CAN start a bash shell with no difficulty. And I can start a pdksh shell within the bash shell with no difficulty. But when I try to make my application I end up with this message (although occasionally I get a Win32 error 87 instead of the 487): C:\cygwin\bin\pdksh.exe (8028): *** couldn't allocate cygwin heap, Win32 error 487, base 0x480000, top 0x4AD000, reserve_size 184320, allocsize 184320, page_const 4096 5 [main] pdksh 6976 fork_parent: child 8028 died waiting for longjmp before initialization rox_pwd: C:/mgc/embedded/bridgepoint/mc3020/bin/rox_init_node[74]: cannot fork - try again I HAVE successfully accomplished a rebase
