Ticket #64368 – Description
initial v1 1 I observe that when building ports under trace mode, the file descriptors given to processes can reach/exceed the default value of `FD_SETSIZE`, which is 1024 when not manually defined before including <sys/select.h>. CMake—and possibly other programs—are compiled without manually defining `FD_SETSIZE` on macOS, and without defining `_DARWIN_UNLIMITED_SELECT` or `_DARWIN_C_SOURCE`. This leads to at least two problems using CMake under trace mode: `Error running link command: Invalid argument` being output; and out-of-bounds memory accesses, one effect being corruption of the `Invalid error` message.1 I observe that when building ports under trace mode, the file descriptors given to processes can reach/exceed the default value of `FD_SETSIZE`, which is 1024 when not manually defined before including <sys/select.h>.
