I copied the gccgo-4.9 package from the ubuntu-toolchain-r/ppa package to trusty-proposed (now waiting for approval). The following testing was done:
- libgcc1: the packages contains the shared library, exports the same symbols, no code changes were done for libgcc1 itself. - the testsuite doesn't show regressions on any architectures (although we should only be interested in regressions in gccgo and libgo; the package in trusty didn't ship a cc1, so we don't have any regressions for the C compiler). - The only package build-depending on gccgo in trusty (juju-core) was successfully rebuilt. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to gccgo-4.9 in Ubuntu. https://bugs.launchpad.net/bugs/1304754 Title: gccgo has issues when page size is not 4kB Status in The GNU Compiler Collection: Fix Released Status in “gcc-4.9” package in Ubuntu: Fix Released Status in “gccgo-4.9” package in Ubuntu: Invalid Status in “gcc-4.9” source package in Trusty: Invalid Status in “gccgo-4.9” source package in Trusty: In Progress Status in “gcc-4.9” source package in Utopic: Fix Released Status in “gccgo-4.9” source package in Utopic: Invalid Bug description: On kernels 3.13-18 and 3.13-23 (there may be others) the kernel is killing gccgo compiled binaries [18519.444748] jujud[19277]: bad frame in setup_rt_frame: 0000000000000000 nip 0000000000000000 lr 0000000000000000 [18519.673632] init: juju-agent-ubuntu-local main process (19220) killed by SEGV signal [18519.673651] init: juju-agent-ubuntu-local main process ended, respawning In powerpc/kernel/signal_64.c: sys_rt_sigreturn is jumping to the badframe: label and executing an unconditional force_sigsegv which is delivered to the userland process. Like C++, gccgo tries to decode SIGSEGV as a nil pointer access and blame some random function that happened to be the top stack frame. Reverting to the 3.13-08 kernel appears to resolve the issue which (weakly) points the finger at the recent switch to 64k pages.
