The attached patch seems to fix the problem for me.
Without that patch, directories which are subdirectories of
directories listed in the config files (/etc/fonts/fonts.conf etc)
were added too late to the list of font directories in "FcConfig
*config". For example, when FcDirScanConfig() was called with the
argument "/usr/share/fonts/bdf" the list of font directories in
config->fontDirs->strs still contained only the higher level
directory "/usr/share/fonts" because only that was listed in the
config files, not the "bdf" subdirectory.
FcDirScanConfig() then calls FcGlobalCacheReadDir() before
adding the subdirectory to the list, FcGlobalCacheReadDir()
calls FcConfigNormalizeFontDir(dir) which returns 0 because the directory
is not yet in the list and then it crashes in strlen(dir) of course.
To fix this, I moved the call to FcConfigAddFontDir (config, dir)
upwards in FcDirScanConfig() to add the directory *before*
FcGlobalCacheReadDir() is called.
