Increase the size of the char buffer. gcc 9.1.1 reports:
|
||
|
||
rc/svsematest/svsematest.c:578:24: warning: ‘%d’ directive writing between 1 and 10 bytes into a region of size 5 [-Wformat-overflow=]
|
||
578 | sprintf(f_opt, "-fr%d", i);
|
||
| ^~
|
||
src/svsematest/svsematest.c:606:5: note: ‘sprintf’ output between 5 and 14 bytes into a destination of size 8
|
||
606 | sprintf(f_opt, "-fs%d", i);
