Log:
[lldb] Handle EOF from `lldb-vscode`
Sometimes (when running lldb-vscode under strace) I get:
read(0, "", 16) = 0
read(0, "", 16) = 0
read(0, "", 16) = 0
...
With this patch testcases finish properly even with strace:
read(0, "", 16) = 0
futex(0x1346508, FUTEX_WAKE_PRIVATE, 2147483647) = 0
stat("", 0x7ffe8f2634c8) = -1 ENOENT (No such file or directory)
--- SIGCHLD {si_signo=SIGCHLD, si_code=CLD_KILLED, si_pid=9124, si_uid=1001,
si_status=SIGINT, si_utime=1, si_stime=0} ---
close(4) = 0
exit_group(0) = ?
+++ exited with 0 +++
