Bug#41952: libc6: SIGILL from fprintf

[kevin.turner@oberlin.edu]

Package: libc6
Version: 2.1.2-0pre1
Severity: normal

At first I thought it was a bug in the game...  then I looked at the
backtrace and saw that GGI was trying to print error messages and the
fatal blow came during the printf, apparently not anything related to
the game or ggi.

Program received signal SIGILL, Illegal instruction.
