That's because -latomic is required in that case, but openmp does not add it to the linker command line. -- You are receiving this mail because: You are on the CC list for the bug.

[ 1254s] [ FAILED ] 1 test, listed below: [ 1254s] [ FAILED ] JSONTest.Integers Essentially, there is a check that an int64_t converted to a double matches a pre-calculated value exactly. This does not work for a large 64-bit integer which cannot be interpreted exactly as a 64-bit double. That's because the integer value is stored in a hardware floating-point register (using the FILD instruction). This register has 80 bits, so it can represent the integer value exactly. This register is then compared with the 64-bit value (loaded into another 80-bit floating-point register from memory using FLD instruction). Of course, the two do not match. It is not an issue on x86-64, because 64-bit XMM registers are used in that case, so there is no extra precision. I believe this unit test is broken, at least on i586. -- You are receiving this mail because: You are on the CC list for the bug.
