#8561 closed defect (fixed)

Segfault when starting to play .nuv recording

Description

I get a segfault almost every time when starting to play .nuv recording recorded from v4l framegrabber card. I suspect either the new audio code is at fault or it is exposing a bug in NVR. The segault appears to be occurring in toFloat16. See the backtrace for details.

(In [25103]) buffer needs to be 16 bytes aligned. Fixes #8561

I'm still seeing what appears to be the same segfault in toFloat16 as shown in gdb2.log.

Are you sure you upgraded ?

0x418b0de9 in toFloat16 (out=0x50720150, in=0x50ea1008, len=512) at audiooutpututil.cpp:217

in is 0x50ea1008, that's not a 16 bytes aligned address. Which just can't happened now following r25103

(In [25107]) Another buffer that needs to be 16 bytes aligned. Fixes #8561

That appears to have fixed it. Thanks.
