z/VM 630vm.ins IPL leads to segfault

[fbi-ranger]

IPL 630vm.ins (Installation IPL) leads to segmentation fault in current version of Hyperion.

HerculesOS: openSUSE 13.2

This is a regression as the IPL works. No additional infromation in hercules.log.

Florian,

Under which Hyperion version did this occur ? Did you use the “-O3” compiler option to generate it ?

I never experienced segmentation faults as I always use the default compiler options, both under Windows and Linux, but I’ve read similar error reports and this not-so-trustworthy “-O3” compiler always gets mentioned.

I responded to your query because z/VM 6.3 (as you mention 630vm.ins) up until yesterday would not install or run under Hyperion. But yesterday I committed a fix to Hyperion so that z/VM 6.3 now should work just fine, at least it does for me now, after a clean rebuilding with the default compiler settings. I’d be interested in your experiences with that latest Hyperion version.

Hi Peter,

Great! Thanks for that hint. I compiled Hercules without -O3 and the error during IPL did not occure anymore. So I can start the installation.
