Since it is related to SwiftShader component, assigning it to capn@ for further triage.

This is caused by a sampler register index being out of range. This can't actually happen in Chrome because we validate them at draw time when applying the state. The fuzzer takes a shortcut and doesn't actually draw anything. So this is benign, but we should probably have a fail-safe at either the shader ASM generation or Reactor routine generation (or both). Anyway, this is all going to change when we switch to using the glslang compiler, so it's not a priority.

ClusterFuzz testcase 6350084528406528 is still reproducing on tip-of-tree build (trunk). If this testcase was not reproducible locally or unworkable, ignore this notification and we will file another bug soon with hopefully a better and workable testcase. Otherwise, if this is not intended to be fixed (e.g. this is an intentional crash), please add ClusterFuzz-Ignore label to prevent future bug filing with similar crash stacktrace.
