RFR [9] 8034181: SIGBUS at Java_sun_nio_ch_SctpChannelImpl_receive0

2014-03-22 Thread Chris Hegarty
The native SCTP implementation assumes that the given byte buffer ( buffer address + position ) is memory aligned. It re-uses the buffer for handling notifications from the SCTP Stack ( as well as for reading data off the socket ). This can result in a SIBGUS on sparc(v9) if the address is not 4

Sorry about the hiccup. Supposedly the bug will work if you get in with user guest PW guest. As for non Windows, I don't know a lot of Windows programmers, only malware analysts. So we'd need to ask somebody in Sun's porting group I think. Or if somebody has a contact at Microsoft. Matthew. --
