make web fails on debug build

[Joe Neeman]

When I build with --enable-debug --disable-optimising, make web fails (with latest git master). I've narrowed it down to the following command:

./out/bin/lilypond -dgs-load-fonts --verbose  -b eps input/regression/utf-
8.ly

Which causes gs (8.50) to barf with:

Invoking `gs   -dNOSAFER   -dEPSCrop  -dCompatibilityLevel=1.4  -dNOPAUSE -dBATCH -r1200  -sDEVICE=pdfwrite -sOutputFile="utf-8-1.pdf" -c .setpdfwrite -f "
utf-8-1.eps"'...GPL Ghostscript 8.50 (2005-12-31)

Any ideas? I've also tried upgrading gs to 8.54, but it still failed. The full output is attached.
