Summary: Regression crash when a function return type is
invalid (following GLSL2 merge)
Product: Mesa
Version: git
Platform: x86 (IA32)
OS/Version: Linux (All)
Status: NEW
Severity: major
Priority: medium
Component: Mesa core
AssignedTo: mesa-dev@lists.freedesktop.org
ReportedBy: cedr...@neonux.com
When a function return type is unknown/invalid the GLSL compiler crashes
instead of issuing a proper "invalid type" error.
This only occurs when the invalid type is return type of a function, not when a
function parameter is an invalid type.
Testcase :
--
foo bar()
{
}
void main()
{
gl_Position = vec4(0.0);
}
