Reviewed by Ryosuke Niwa.
Source/WebCore:
In r275668, I added null-checks for the AudioContext in AudioParam, now that it holds a WeakPtr to its
context. However, I missed a null-check in AudioParam::exponentialRampToValueAtTime(). This patch adds
the missing check.
Test: webaudio/AudioParam/audioparam-exponentialRampToValueAtTime-nocontext-crash.html
* Modules/webaudio/AudioParam.cpp:
LayoutTests:
Add layout test coverage.
* webaudio/AudioParam/audioparam-exponentialRampToValueAtTime-nocontext-crash-expected.txt: Added.
* webaudio/AudioParam/audioparam-exponentialRampToValueAtTime-nocontext-crash.html: Added.
