Roy Sundahl	90b4d1bcb2	[fuzzer] Use puts() rather than printf() in CopyFileToErr() ... CopyFileToErr() uses Printf("%s", ...) which fails with a negative size on files >2Gb (Its path is through var-args wrappers to an unnecessary "%s" expansion and subject to int overflows) Using puts() in place of printf() bypasses this path and writes the string directly to stderr. This avoids the present loss of data when a crashed worker has generated >2Gb of output. rdar://99384640 Reviewed By: yln, rsundahl Differential Revision: https://reviews.llvm.org/D146189	2023-03-28 14:19:35 -07:00
