Re: [Texmacs-dev] RE: Texmacs segfault

[Felix Breuer]

Hello!

My texmacs works when selecting text, at least it has not crashed yet.
It does segfault upon saving, though.

Is there any way to compile texmacs with debugging symbols? The
configure-script does apparently not support --enable-debug=yes. So, is
there a way to do this?

I have tried versions 1.0.0.16 and 1.0.0.18 and got the same error each
time.

Regards,
Felix.
