Hi,

 

When trying to build gcc using make with -j N, I'm finding that make will
hang on 64-bit Cygwin. I don't see this problem with 32-bit Cygwin on the
same PC. When it hangs, there are N make processes reported in task manager
that are using 0% CPU, that appear to be waiting for N sh.exe programs also
using 0% CPU. Non parallel builds seem to be OK.

 

Any idea what might be wrong? Cygwin install is up to date. Windows 10.

 

Thanks,

Jon
