Created attachment 431826 [details] emerge --info + backtrack information Hi, I have a weird problem with the up-to date numba-0.25. It's compiled from the portage tree with The installation was apparently flawless. However, when I try to run scripts from the numba/examples directory, the following error appears [...]:~/numba/examples> ./example.py *** Error in `/usr/bin/python2.7': free(): invalid pointer: 0x00007f1c74af4200 *** [...] [...]:~/numba/examples>python2.7 ./example.py *** Error in `python2.7': free(): invalid pointer: 0x00007ffa7730a200 *** [...] My machine is AMD Phenom II based. I have attached the emerge --info, as well as the rest of error information dumped. numba portage # required by numba (argument) dev-python/numba ~amd64 # required by dev-python/llvmlite-0.10.0::gentoo # required by dev-python/numba-0.25.0::gentoo # required by numba (argument) sys-devel/llvm ~amd64 # required by dev-python/numba-0.25.0::gentoo # required by numba (argument) dev-python/llvmlite ~amd64 I installed numba from portage, since none of PyPy or a direct install from the github tree does not work with the up-to date package. I have checked these two methods under OpenSuse 42.1, still any progress. Many thanks for your interest and help. Dianthus
why is the backtrace hard wrapped?
Created attachment 432316 [details] updated emerge --info, more simple test script and backtrack info without wrapped lines A new test data after recompiling gcc to 4.9.3 and the following packages: sys-devel/llvm-3.7.1-r1:0/3.7.1 dev-python/llvmlite-0.10.0:0 dev-lang/python-2.7.10-r1:2.7 dev-python/numba-0.25.0:0 Yet the same weird error occurs...
(In reply to Alex Xu (Hello71) from comment #1) > why is the backtrace hard wrapped? Sorry, it's my fault. I updated the file and data. The same type of error occurs in my second machine [X]:~>emerge --info Portage 2.2.26 (python 2.7.10-final-0, default/linux/amd64/13.0/no-multilib, gcc-4.9.3, glibc-2.22-r4, 3.7.10-gentoo-r1 x86_64) ================================================================= System uname: Linux-3.7.10-gentoo-r1-x86_64-AMD_Opteron-TM-_Processor_6272-with-gentoo-2.2 KiB Mem: 16413836 total, 10889404 free KiB Swap: 0 total, 0 free with a newer architecture and an ancient kernel, thought the numba-related packages are the same. I have also tested it with gcc 4.8.5.

are you still suffering this?

I am sorry to answer so late, since after a few attempts to run the codes, finally I gave up and looked for cython and alternatives. Now I see that numba may work as well. We are back in the game :) So the bug may be closed. Best wishes, Dianthus
