The previous trace is wrong, sorry
A correct place is

if (const_wanted)
tcc_error("expected constant");

save_regs(0); <<<<<<<<<<<<<<<

inside as GCC does */
block(NULL, NULL, NULL, NULL, 0, 1);
skip(')');
} else {
gexpr();
skip(')');
}
This is a save_regs(0) which generate a code when nocode_wanted=1
When
if(!nocode_wanted)
save_regs(0);
then there is no error messages but a test program still hangs
Of course, because the whole parsing of the ({block}) still generates
code. The nocode_wanted hack currently doesn't work for statement
expressions, and as Edmund says deserves a little thought if it's applied
at the right level currently (well I think it's clear that it isn't, but
the question what the right level is remains).
Ciao,
Michael.
