Subject: glsl: Add glcpp tests for a macro used twice
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=64fd26a8a812f66f1291d897df7953b8ac9e2f1b;p=mesa.git

glsl: Add glcpp tests for a macro used twice

This test cases exposes a bug as described in this bug report:

	"ralloc.c:78: get_header: Assertion `info->canary == 0x5A1106'
	failed." when using a macro in GLSL
	https://bugs.freedesktop.org/show_bug.cgi?id=45082

Clearly, some memory is getting (incorrectly) freed on the first macro
invocation, leading to problems with the second macro invocation.
