Segfault on aggregation over large composite types

[Dimitar Misev]

Aggregation on composite types (in particular with a lot of struct members) like

struct FloatPixel { float band1, band2, band3, band4, band5, band6, band7, band8, band9, band10, band11, band12, band13, band14, band15, band16, band17, band18, band19, band20, band21, band22, band23, band24, band25, band26, band27, band28, band29, band30, band31, band32, band33, band34, band35, band36, band37, band38, band39, band40, band41, band42, band43, band44, band45, band46, band47, band48, band49, band50, band51, band52, band53, band54, band55, band56, band57, band58, band59, band60, band61, band62, band63, band64, band65, band66, band67, band68, band69, band70, band71, band72, band73, band74, band75, band76, band77, band78, band79, band80, band81, band82, band83, band84, band85, band86, band87, band88, band89, band90, band91, band92, band93, band94, band95, band96, band97, band98, band99, band100, band101, band102, band103, band104, band105, band106, band107, band108, band109, band110, band111, band112, band113, band114, band115, band116, band117, band118, band119, band120, band121, band122, band123, band124, band125, band126, band127, band128, band129, band130, band131, band132, band133, band134, band135, band136, band137, band138, band139, band140, band141, band142, band143, band144, band145, band146, band147, band148, band149, band150, band151, band152, band153, band154, band155, band156, band157, band158, band159, band160, band161, band162, band163, band164, band165, band166, band167, band168, band169, band170, band171, band172, band173, band174, band175, band176, band177, band178, band179, band180, band181, band182, band183, band184, band185, band186, band187, band188, band189, band190, band191, band192, band193, band194, band195, band196, band197, band198, band199, band200, band201, band202, band203, band204, band205, band206, band207, band208, band209, band210, band211, band212, band213, band214, band215, band216, band217, band218, band219, band220, band221, band222, band223, band224, band225, band226, band227, band228, band229, band230, band231, band232, band233, band234, band235, band236, band237, band238, band239, band240, band241, band242, band243, band244, band245, band246, band247, band248, band249, band250, band251, band252, band253, band254, band255, band256, band257, band258, band259, band260, band261, band262, band263, band264, band265, band266, band267, band268, band269, band270, band271, band272, band273, band274, band275, band276, band277, band278, band279, band280, band281, band282, band283, band284, band285, band286, band287, band288, band289, band290, band291, band292, band293, band294, band295, band296, band297, band298, band299, band300, band301, band302, band303, band304, band305, band306, band307, band308, band309, band310, band311, band312, band313, band314, band315, band316, band317, band318, band319, band320, band321, band322, band323, band324, band325, band326, band327, band328, band329, band330, band331, band332, band333, band334, band335, band336, band337, band338, band339, band340, band341, band342, band343, band344, band345, band346, band347, band348, band349, band350, band351, band352, band353, band354, band355, band356, band357, band358, band359, band360, band361, band362, band363, band364, band365, band366, band367, band368, band369, band370, band371, band372, band373, band374, band375, band376, band377, band378, band379, band380, band381, band382, band383, band384, band385, band386, band387, band388, band389, band390, band391, band392, band393, band394, band395, band396, band397, band398, band399, band400, band401, band402, band403, band404, band405, band406, band407, band408, band409, band410, band411, band412, band413, band414, band415, band416, band417, band418, band419, band420, band421, band422, band423, band424, band425, band426, band427, band428, band429, band430, band431, band432, band433, band434, band435, band436, band437, band438; };

results in:

[Peter Baumann]

maybe try to split it into several queries where each one addresses a smaller number of bands, small enough to work.

[Dimitar Misev]

Won't fix in RNP, new protocol in 9.1 will fix it.
