Apologies for what is going to be quite light on details as bug reports go, but I've only just noticed it and I haven't got a simple testcase yet.
As the subject line says, heap_chunk_in_mb=1536 breaks expect. The situation that I'm seeing this in is when attempting to run the binutils testsuite. With heap_chunk_in_mb set to 1536, "make -k check" gets as far as the very first *.exp file in the binutils testsuite (binutils-all/ar.exp), and then sits there, spinning its wheels and eating CPU. It doesn't happen if heap_chunk_in_mb is set to 1024, 1280, 1408, 1520 and the test run completes. It does happen at 1535, and 1532. At 1528 to 1530 it gets a few testcases further into the run before stalling. Probably the exact cut-off point is environment-dependent. Sorry not to have much information, but at least there's a simple workaround: turn it down a bit. If I find out more I'll report back. cheers, DaveK -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
