Re: [ptxdist] Segmentation fault with ptxdist-2020.05.0

[Mircea Ciocan <m.ciocan@ppc-ag.de>]

More information about the subject:

I've repeated the compilation with all releases since 2020.02.0, the 
same config and machine as described under (sorry for top posting):

- 2020.02.0 - works OK

-2020.03.0 - works OK

-2020.04.0 - crashes, bash segfault.

-2020.05.0 - crashes, same bash segfault, in the same place.

So the regression is between 2020.03.0 and 2020.04.0, I'll try a diff, 
maybe I can spot what went wrong, but I could use your kind help.

The main problem is that the older releases as 2020.05.0 doesn't compile 
the toolchain correctly.

Best regards,

Mircea
