[ft-devel] mysterious crash

[Werner LEMBERG]

The attached (invalid) font causes a crash on my Linux box if called
with

  ftview 20 test122

gdb also shows the crash but doesn't show anything suspicious.
Interestingly, valgrind by default passes fine, but using the
--alignment=16 option yields

  Address 0x457621C is not stack'd, malloc'd or (recently) free'd

However, I'm apparently too stupid to find the reason...

Can someone help, please?
