I have found the problem in the meantime ... it's my mistake, sorry about the noise :( The problem is that I did not explicitly zero the arrays in main(), so they apparently contained NaN or similar nastinesses for the small ARRSZ, and "usual" numbers for large ARRSZ. Of course the processor chokes on the "unusual" numbers and takes much longer to execute the code. I'm not sure whether the zeroing should be added for the regression test case ... but since you check for compiler diagnostic and do not try to run the resulting executable that's probably not necessary. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44423
