[Numpy-discussion] Compiler change for Windows version between 18.104.22.168 and 1.0.4?
Tue Dec 18 13:07:34 CST 2007
I have found a bug in numpy-1.0.4. The bug is a crash when doing
linalg.inv() on a Windows machine. The machine is an old Pentium 3
machine. The error report indicates an invalid op code. Details
about this bug are in the numpy tracker under ticket 635.
Numpy-22.214.171.124 doesn't crash when running the same code.
I installed the pre-built binaries available from numpy's SF site.
Since the binaries were built by you, I can only suspect that the
problem involves using a different compiler to build 1.0.4. I suspect
the new version was built with a compiler which emitted op codes the
old P3 chip couldn't handle.
Can the developers confirm or deny my hypothesis?
