Thank you for your feedback.
This error "couldn't commit memory for cygwin heap" usually happens when the
emulated "fork" system call can't recreate the exact memory layout for a child
process.
Besides rebasing the msys-1.0.dll and running rebaseall, I can only suggest
removing any anti-virus software, since they are known to inject code into
running DLLs, causing interference with the MSYS fork mechanism.
The original implementation of "fork" in MSYS comes from the Cygwin project.
Meanwhile, Cygwin has evolved and is likely to have fewer problems regarding
this error. I would be interested to know if MSYS2 (msys2.org), which closely
tracks modern Cygwin, solves your issues. Note that MSYS2, like Cygwin, doesn't
run in Windows 95 and XP.
Regards,
Cesar

Ticket details:
Hello, When i try to compile a project(big one) make always fails at some point
with the following error:
C:\MinGW\msys\1.0\bin\make.exe: *** couldn't commit memory for cygwin heap,
Win32 error 0
after starting a build again it continues and finishes the build. However in
some situations i can not "work around" this.
This is the version of MSYS: C:\windows\system32>uname -a MINGW32_NT-6.1
BGHCZC5281GJ4 1.0.19(0.48/3/2) 2016-07-13 17:45 i686 Msys
Version of MINGW: MINGW32_VERSION 5000002L
I have tried several suggestions to correct the issue: 1.tried rebasing the
msys-1.0.dll 2.tried rebaseall from rebase package 3.tried reinstalling mingw
4.tried setting max heap(peflags --cygwin-heap=2048 make.exe) from rebase
package. 5.increased the vritual paging file to 20gb. 6.checked in PATH
variable that only one MINGW path is listed. 7.upgraded mingw to latest
libraries
None of these made any difference.
Please help.
