Public bug reported:
In very rare cases during compiling of some c-sources tendracc is fail
with inner error.
For example, compiling of tendra_nil.c on 10.04.4 and 12.04.1:
int f(int a, int b) {
return (b & ~a) | ~b;
}
int main() {
f(0, 0);
return 0;
}
$ tendracc tendra_nil.c
tcc: Error: Caught signal 11 in
'/usr/lib/TenDRA/machines/linux/2.6.24-25-server/80x86/bin/trans'.
I found and fix mistake without good understanding of tendracc. But
because of fix is influence only on situations which must not appear in
normal cases, it must not broke main logic.
** Affects: tendra (Ubuntu)
