Commenting out 2 ifs (not nested) makes it compile again:
|
||||||
|
|
||||||
|
#+BEGIN_CENTER
|
||||||
|
// if(hdr.udp.isValid()) {
|
||||||
|
// #ifdef USE_NICO_DELTA_CHECKSUM
|
||||||
|
// delta_udp_from_v6_to_v4();
|
||||||
|
// #else
|
||||||
|
// meta.chk_udp_v4 = 1;
|
||||||
|
// #endif
|
||||||
|
// }
|
||||||
|
// if(hdr.tcp.isValid()) {
|
||||||
|
// #ifdef USE_NICO_DELTA_CHECKSUM
|

// delta_tcp_from_v6_to_v4();

// #else
|

Only enabling the following triggers the bug again:
|

|
|

|
#+BEGIN_CENTER
|
||||||
|
if(hdr.udp.isValid()) {
|
||||||
|
#ifdef USE_NICO_DELTA_CHECKSUM

#else
|

meta.chk_udp_v4 = 1;

#endif
|
||||||
|
}
|
||||||
|
|
||||||
|
#+END_CENTER
|
||||||
|
|
||||||
|
Even this code is enough:
|
||||||
|
|
||||||
|
#+BEGIN_CENTER
|
||||||
|
if(hdr.udp.isValid()) {
