Subject: glsl2: strdup the field names used in dereference_record.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=fade78edcbff1e0ae24a1e2c455be2cc7932ee9c;p=mesa.git

glsl2: strdup the field names used in dereference_record.

Otherwise, after linking and freeing the old data, the pointer would
dangle.  Partial fix for glsl1-struct*.
