gold linker issues with PostGIS cunit tests
I've had a few hours of frustration trying to debug a segfault triggered by PostGIS cunit tests to find it was gold's fault instead. This is : binutils-gold 2.20.1-3ubuntu5 To reproduce: git clone git://github.com/strk/postgis.git cd postgis && git checkout 728e94ab0325a89fa3ac4548d8617d144a0ab717 ./autogen.sh && ./configure && make all cd liblwgeom/cunit && make check Expected result: no segfault Obtained result: segfault I've spent hours moving code around in cu_tester.c or some tests and could handle to avoid the segfault, but it made no sense. Valgrind reported somethign like: ==31508== Bad permissions for mapped region at address 0x4885E0 And gdb found it comin from strcmp or strlen... Linking cu_tester with "the other" linker works fine. --strk; () Free GIS & Flash consultant/developer /\ http://strk.keybit.net/services.html ___ bug-binutils mailing list bug-binutils@gnu.org http://lists.gnu.org/mailman/listinfo/bug-binutils

You need to use the gold from the binutils 2.21 release instead. See https://bugs.launchpad.net/ubuntu/+source/binutils/+bug/673893 .
