The test case can be simplified another bit.
Another source file example:
my_structure x = { 2 * 3, 0 };
Questionable test result (with the software combination “Coccinelle 1.3-00083-g4093aad2d”):
Markus_Elfring@Sonne:…/Projekte/Coccinelle/Probe> spatch --parse-c test1-multiplication_in_structure_initialiser.c
…
(ONCE) CPP-TYPEDEF: promoting:(201) my_structure on line 1
-----------------------------------------------------------------------
NB total files = 1; perfect = 1; pbs = 0; timeout = 0; =========> 100%
nb good = 0, nb passed = 0 =========> -nan% passed
nb good = 0, nb bad = 0 =========> -nan% good or passed
Regards,
Markus
