>Description:
While running some programs under electricfence (pkgsrc 2.0.5, manually
installed 2.2.0) control, i noticed some unexpected crashes. gdb only
report a `strcat' call, without a backtrace. The same program, works fine
on -current alpha and i386 + electricfence.

Reverting `strcat.S' to rev 1.2 seems to solves this problem.
