Comment (by gk):

 Replying to [comment:56 mingwandroid]:
 > I didn't notice the 64 bit python compile being especially slow when I
 tested it but then again python compiles very quickly anyway so it could
 have taken a lot longer than a 32 bit compiler. Can you use strace or some
 thing like that to figure out which part of the compilation is slow? I.e.
 clang or the assembler or the linker?

 I attached the strace output I got while compiling sqlite.c (I added the
 time it took + the actually executed command (in mozilla-
 esr24/db/sqlite/src) above the strace output) on (non-VM) Ubuntu 12.04
 (once 32bit, once 64bit). There are differences (mmap vs. mmap2 e.g.) but
 I am not sure how to map those to the latency of the 64bit build.

 also the arrival of an SSD drive causing me to reinstall several OSes.

 No problem :)

 > The crash looks like a NULL pointer access to me. Is it possible to
 enable more complete diagnostic output in Firefox?

 Not without compiling it with debug symbols and without optimization. If I
 don't get the 64bit build running today I'll start a debug Firefox build
 in the afternoon to have the results tomorrow morning...

 issues.

 Thanks, that's really appreciated.
