Subject: egl_xlib: Pass RTLD_LAZY to dlopen.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=293f576db7cf3f411c2eeb0a72232d25b631dcd1;p=mesa.git

egl_xlib: Pass RTLD_LAZY to dlopen.

dlopen manpage mandates that either RTLD_LAZY or RTLD_NOW flags must be
passed. Not doing so was causing a NULL return on debian unstable x86-64.
