There is a code in the tccgen.c marked
/* XXX: this test is incorrect for local initializers
beginning with ( without {. It would be much more difficult
to do it correctly (ideally, the expression parser should
be used in all cases) */
This code is not executed for the OK cases. There is a patch attached
which remove this code. A test files are attached too. A J compiler
test is executed OK after this patch. Only one problem arises after
this, it is an empty struct initialization. Any tips to solve this
problem?
