yes that was the fix I had in mind. > The least invasive workaround would be to export MALLOC_CHECK=2 at build > time (i.e. in debian/rules), as this causes glibc to abort without > attempting to produce a backtrace when it detects internal malloc > corruption.

In practice this shouldn't be an issue because we only build static binaries in very few cases. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to evolution-data-server in Ubuntu. https://bugs.launchpad.net/bugs/1266492 Title: ld:i386 crashes with -static -fPIE -pie Status in Embedded GLIBC: Incomplete Status in “binutils” package in Ubuntu: Confirmed Status in “eglibc” package in Ubuntu: New Status in “evolution-data-server” package in Ubuntu: Triaged Status in “xorg-server” package in Ubuntu: Triaged Status in “binutils” source package in Trusty: Confirmed Status in “eglibc” source package in Trusty: New Status in “evolution-data-server” source package in Trusty: Triaged Status in “xorg-server” source package in Trusty: Triaged Bug description: Making a simple file conftest.c with the following contents: int main() { return 0; } And then compiling it on i386 with gcc -fPIE -pie -static conftest.c returns: *** Error in `/usr/bin/ld': corrupted double-linked list: 0x08dddb38 *** This breaks compilation xorg-server on i386.
