Package: tcc Version: 0.9.27~git20140923.9d7fb33-3 Severity: important Dear Maintainer,
I'm testing tcc to compile the GMP library (https://gmplib.org/) and unfortunately I have to report miscompilation. The whole library is quite a complex piece of code, so I tried to obtain a minimal chunk that gets miscompiled by the currently packaged tcc. The simple program below, when executed with tcc gives a "Bus Error". $ cat test-tcc.c #include <stdio.h> int main (int argc, char **argv) { unsigned ip[1 ? 1 : 1]; do {} while (0); ip[0] = 1; if (ip[0]) { do { do {} while (0); ip[0] -= 0; } while (0); putchar('\n'); } return 0; } $ tcc -run test-tcc.c Errore di bus If I downgrade to tcc_0.9.26-1, the program compiles and runs flawlessly.
