Public bug reported:
The X Resource Manager config file syntax allows entries to be continued
across newlines. To do that, one preceeds the newline with a backslash.
If such entries are present in the current resource database, the
FontForge code that parses the resources fails (or it can fail
sometimes, at least). The proximal cause is a call to the routine
"copyn()" in the file Unicode/memory.c, such that the "n" parameter is
negative. That makes the code think that "galloc()" has failed, and it
exits.
The code that makes the bogus "copyn()" call is the function
"GResourceAddResourceString()" in gdraw/gresource.c. I didn't fully
analyze the code that's trying to parse the string, but it's clearly
making assumptions about the nature of the resource database lines that
aren't true in the case of a continued, multi-line entry.
