[1.20.0] 'sed' segfaults while trying to match wildcards (fwd)

[Tomasz Czapiewski]

Problem is caused by commit: d29ae7e071a11c51436922654c2de73a8ac36333
('sed: fix possible case of signed char bug; expand debugging printouts')

After reverting this commit problem gets solved.

Confirmed on x86_64 (dynamicly linked with glibc) and MIPSel (dynamicly 
linked on uClibc 0.9.29).

# echo "anything" | sed 's/\t*//g'
Segmentation fault

Worked fine on 1.19.3.
