It is invalid because of tabs inserted into the template that cause the functions to have syntax / indenting errors. I attempted to install happy to patch it, but happy will not compile either because of the tabs. I think clang's CPP is inserting tabs into lines with > 8 spaces of indentation. Also the comment lines in the template of this form are invalid for clang and cause it to fail. {{{ # 5 comment }}} -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/8493> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

It fails with: {{{ ghc: error while loading shared libraries: libgmp.so.3: cannot open shared object file: No such file or directory }}} The problem is that the current Debian stable is Wheezy and it uses a newer version of libgmp. Proposed solution: Recompile on a recent Debian stable (Wheezy). Applies to x86_64 as well, most likely all architectures supported by Debian are affected. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/8085> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

This situation sounds exactly like [https://ghc.haskell.org/trac/ghc/ticket/7344 this bug] reported 17 months ago. Symptoms are 'pandoc --version' hangs and consumes memory until the process eventually dies with an OOM error. This seems to only happen when LC_ALL is set in the environment, and only when running the statically linked pandoc. {{{ $ uname -a Linux server 3.5.0-43-generic #66~precise1-Ubuntu SMP Thu Oct 24 14:52:23 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux $ wget https://s3.amazonaws.com/rstudio-buildtools/pandoc-1.12.3.zip $ unzip pandoc-1.12.3.zip $ file pandoc-1.12.3/linux/debian/x86_64/pandoc pandoc-1.12.3/linux/debian/x86_64/pandoc: ELF 64-bit LSB executable, x86-64, version 1 (GNU/Linux), statically linked, for GNU/Linux 2.6.15, BuildID[sha1]=0x9bc69f51b7c213cf58e9f8692f4b46f9f05fb723, not stripped $ LC_ALL=C strace -e trace=open,close pandoc-1.12.3/linux/debian/x86_64/pandoc --version open("/usr/lib/gconv/gconv-modules.cache", O_RDONLY) = -1 ENOENT (No such file or directory) open("/usr/lib/gconv/gconv-modules", O_RDONLY) = -1 ENOENT (No such file or directory) --- SIGVTALRM (Virtual timer expired) @ 0 (0) --- --- SIGVTALRM (Virtual timer expired) @ 0 (0) --- --- SIGVTALRM (Virtual timer expired) @ 0 (0) --- --- SIGVTALRM (Virtual timer expired) @ 0 (0) --- ^C--- SIGINT (Interrupt) @ 0 (0) --- }}} Note this problem does not occur if I run an older dynamically linked pandoc under the same circumstances. {{{ $ /usr/bin/pandoc --version pandoc 1.9.1.1 Compiled with citeproc-hs 0.3.4, texmath 0.6.0.3, highlighting-kate 0.5.0.5.
