Subject: glsl2: Fixed cloning of ir_call error instructions.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=3894fddccc3a6da91513b49142a8f0dbbf8aa448;p=mesa.git

glsl2: Fixed cloning of ir_call error instructions.

Those have the callee field set to the null pointer, so
calling the public constructor will segfault.
