[Pkg-julia-devel] Bug#971570: Bug#971570: Bug#971570: julia: libgit2 1.0 transition

[Ximin Luo]

Hi Norbert,

In October I did a build which failed with SEGV:

~~~~
OPENBLAS_NUM_THREADS=1 OMP_NUM_THREADS=1 ./sblat1
 Real BLAS Test Program Results


 Test of subprogram number  1             SDOT 

Program received signal SIGSEGV: Segmentation fault - invalid memory reference.

Backtrace for this error:

Now that I look at it closer, perhaps this is unrelated to libgit2 and the problem was already fixed in the meantime. If not, the full log is attached for you to investigate. In the meantime I will let the release team know not to block the libgit2 transition on julia.
