### Description
version:php 7.4.27
file: SAPI.c
function: sapi_send_headers
code:
if (sapi_module.send_headers) {
retval = sapi_module.send_headers(&SG(sapi_headers));
} else {
retval = SAPI_HEADER_DO_SEND;
}
switch (retval) {
case SAPI_HEADER_DO_SEND: {
......
sapi_module.send_header(&http_status_line, SG(server_context));
}
describe:
I didn't set sapi_module.send_headers in sapi_module_struct, so this function is NULL.
retval = SAPI_HEADER_DO_SEND;
But call sapi_module.send_header in this switch，it could cause crash.
