Description timvdkerkhof 2011-10-24 12:56:31 UTC

Valgrind exits with this error:
vex amd64->IR: unhandled instruction bytes: 0xC5 0xF9 0x57 0xC0 0xC5 0xFA 0x10 0x15

Running the same code on other computers does not generate the problem. So far this error only occurred when using the live555 RTSP library (http://www.live555.com/).

The full output of valgrind with -v -v options is attached.
