Bug#178790: gcc sig11 - no longer reproduced, hardware problem?
Today (2 reboots down the road), the very same cmdline in the very same place (although untarred again into a different directory) goes flawlessly. I am sorry to not have applied the sig11 FAQ techniques on the spot during the original submission. (I'm talking about http://www.tldp.org/FAQ/sig11/html/index.html ) What mislead me was that originally I tried the compilation several times (with cleaning the whole tree, or just on the spot), and it ALWAYS stopped on the same file. But the FAQ explains this - I should have forced the gcc tools and the sources out of the cache before the recompilation, which I haven't done. The reason that I got back to it is that another bug (Bug #181153, which I now CC to as well) raised a strong suspicion of the maintainer that I might have a hardware problem, so I got back to revising all the bugs filed from this machine. Coincidence of 2 bugs with a strong possibility of a hardware problem is very suspicious. I'll subject the machine to severe checks and will report if any new stuff surfaces. Right now it has 6 days uptime w/o any problems since the last reboot (the reboot was from the OOPS in Bug #181153). /me LARTing myself heavily on the head Sorry for having wasted your time in the (most likely) case it's a hardware problem on my end.

if the type of 'a' is changed to int, it works as expected.

Works as who expected? Where is the bug? Please quote which part of
the C standard is violated. You got an address, why are you unhappy?

GNAT 3.15p
Hi, GNAT 3.15p has been released last November and it is still not packaged in Debian. Since, the GNAT from GCC tree is still not stable enough, I'd suggest that we keep on updating the ACT public release. Jon Ward told he was packaging it but nothing seemed to happen. Is anyone still working on this or should I give it a try (I'm not the best skilled though)? Cheers, -- Jérôme Marant http://marant.org
