alexrp commented 6 years ago

I recall having run into this issue in the past. I tend to think it's actually a libedit bug. I don't know if OS X has libreadline available, but if it does, I would recommend remapping the libedit reference in sdb.exe.config to libreadline.dylib, as libreadline is generally more stable, less buggy, and has more features.

callmekohei commented 6 years ago

Hello! I'm callmekohei!

So, you are right!

sdb/mono just work well.

Thank you!

I do following:

/// change libedit ---> libreadline
<configuration>
    <dllmap dll="libedit" target="libedit.so.2" os="!windows" />
    <dllmap dll="libedit" target="/usr/local/Cellar/readline/7.0.3_1/lib/libreadline.7.0.dylib" os="osx" />
</configuration>
