[aspell-devel] Aspell (0.60.6.1) bug on finding suggestions for dotted numeric word

[Guido Trentalancia]

Hello !

I am hitting an aspell bug when the application tries to find
suggestions for a dotted numeric "word" (e.g. 2.2.02.148).

Here is the stack trace from gdb:

Thread 1 "evolution" received signal SIGSEGV, Segmentation fault.
