[tlbuild] dvisvgm segfaults on linux x86_64 when compiled with gcc 4.5

[François Charette]

Hello all,

When compiled with gcc 4.5 on linux x86_64, dvisvgm compiles ok but the resulting binary 
segfaults when ran on any dvi file.
See http://bugs.archlinux.org/task/20199
I have also submitted a bug report upstream at
https://sourceforge.net/tracker/?func=detail&atid=762580&aid=3031498&group_id=145640

It might well be a compiler bug actually, so this is not something of immediate concern to 
this list, but I am just enquiring here in case someone might be able to provide a 
solution (besides the trivial statement ""use gcc < 4.5").

Thanks in advance,
François
