I overlooked there was a gpg related bug here. Anyway gpg-agent works with the latest pth now - the abort was due to FORTIFY_SOURCE enabled extra checks in every longjmp call.
There is no bug in glibc/eglibc , but pth relies on some tricks which are not guaranteed to work and indeed they fail starting with glibc2.11 when built with FORTIFY_SOURCE - this is documented in the pth sources and the paper quoted in comments in this bug. ** Changed in: gnupg2 (Ubuntu) Status: Invalid => Fix Released -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/599862 Title: pth_init() aborts on armel with "longjmp causes uninitialized stack frame" -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
