------- Comment #10 from dominiq at lps dot ens dot fr 2009-12-08 09:56 ------- I had a look at the problem and found that it is due to the -lm flag used in the test suite. The test in comment #9 gives for x86_64-apple-darwin10:
[macbook] f90/bug% a.out 2 0 [macbook] f90/bug% gcc45 pr42074.c -lm [macbook] f90/bug% a.out inf 0 Abort and tgcc.dg/torture/builtin-math-7.c passes when it is compiled manually without -lm. Note that gcc version 4.4.2 (GCC) gives the same results, but not gcc version 4.2.1 (Apple Inc. build 5646) (dot 1) Target: i686-apple-darwin10: [macbook] f90/bug% gcc pr42074.c -lm [macbook] f90/bug% a.out 2 0 These tests pass on powerpc-apple-darwin9 with gcc4.5 rev.155054. I don't have access right now to *86*-apple-darwin9 and older versions of gcc, but I'll check on it tonight. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42074
