crash file
Hello,
I detect the exception in strip-v2.30 with clang-8.0 and the following
configuration:
$ CFLAGS="-fsanitize=address" CXXFLAGS="-fsanitize=address" ./configure
--disable-shared && make -j
Execute strip with the input in the attachment, then the crash occurs with the
stack message by address sanitizer:
strip -o <files> <input>
AddressSanitizer:DEADLYSIGNAL
