In one such case, Linus Torvalds refused to recognize any GNU C Compiler (GCC) version after a certain date, on the grounds that later versions produced bad machine code.
Relationships have become a lot less strained between the two projects since then. However, the question of mending fences does sometimes arise. And it's not always clear whether a problem in the Linux kernel would be best solved by changing the kernel source code or changing the compiler source code. Sometimes the best answer may be simply whatever avoids war.
