Dear all,
I stumbled upon a bug where icpc apparently causes a loop not to be executed. I've attached a minimal example which reproduces the behavior. I've tested with icpc 15.0.3 20150407. The bug is present with -O2 and -O3, but not -O1 nor -Os:
gentryx@neuromancer ~ $ # expected output:
10:49:11 - 0
gentryx@neuromancer ~ $ g++ -O3 test.cpp -o test && ./test
max: (250, 150), min: (150, 50)
10:49:19 - 0
gentryx@neuromancer ~ $ # buggy behavior:
10:49:41 - 0
gentryx@neuromancer ~ $ icpc -O2 test.cpp -o test && ./test
max: (150, -1000), min: (1000, 50)
10:49:45 - 0
gentryx@neuromancer ~ $ icpc -O3 test.cpp -o test && ./test
max: (150, -1000), min: (1000, 50)
10:49:48 - 0
