- dcc_gcc_rewrite_fqn: avoid heap corruption
-
- On ALT Linux I've run into the following bug:
-
- distcc gcc -Wall -std=gnu89 -I. -O2 -o hello.o -c hello.c
- free(): invalid next size (fast)
- Aborted (core dumped)
-
- Apparently dcc_gcc_rewrite writes beyond the allocated memory:
-
- valgrind --leak-check=full -v ./distcc gcc -Wall -std=gnu89 -I. -O2 -o hello.o -c hello.c

- and ALT Linux' hardened glibc does not quite like that.
- Correctly compute the `newcmd_len` to avoid the problem.

-From: Gordon Malm <gengor@gentoo.org>
-
-Make distcc client pass -D__KERNEL__ macro. Hardened GCC uses this
-macro to determine if code intended to be run in-kernel is being compiled.
-If the code is kernel code, certain compile flags are not applied.
-
-When using distcc to build kernel code (modules, etc.) without this patch,
-the distccd host doesn't get passed -D__KERNEL__. Consequently, gcc on
-the distccd host applies all kinds of flags that it shouldn't.
