I have encountered two compiler bugs in my (almost) 40 year career. In about 1988, a bug in Apple's MPW Pascal compiler. I refused to believe it was a compiler bug, until I finally inspected the generated code. IMO the only way to be taken seriously about a compiler bug is to distill the defective compiler behavior down to a short (like one page) example. Also helpful is to show the generated code and how it is wrong. Bug was acknowledged and fixed. In the mid 1990s, dabbling with C++ on (classic) Mac, I upgraded to a (name brand withheld) version 8.0 C++ compiler. The generated code behavior was obviously wrong. To make matters worse, it was possible to crash the compiler. The number of problems with that compiler were so bad that I simply ditched that compiler, and it didn't last much longer commercially. Sad, because its predecessor compilers (mostly C and Pascal) had been very good.
