[Bug-gnubg] Bug: crash when importing irregular format text after a match started

[Daisuke Takahashi]

Hi,

After starting a new match, gnubg crashes when I attempt to import an 
irregularly formatted text file (e.g., a score at [1]).
ImportMat() (import.c:1177) frees all the lMatch elements (import.c:1184), then 
replaces it by a newly allocated match data and update plGame. But when it 
failed to import a match from the input file, nothing will be allocated and the 
plGame points to the already freed region. The backtrace is attached on this 
mail.
Thank you very much.

Regards,
Daisuke Takahashi
