Voltron views do not appear at all, no blank screen, just a disappearing cursor. #265

Open bitshiftnetau opened 4 years ago

bitshiftnetau commented 4 years ago

Executing 'voltron view disasm/stack/bp' doesn't even render a blank screen, just another line in the terminal with no blinking cursor and then Ctrl+c out of that screws the whole terminal and entering any command doesn't show any text or cursor.

It seems that arm toolchain 7.2 does not work with Voltron for one reason or another. Nothing displays, nothing crashes, nothing happens. That's fine.

However, compiled with gcc 8.3 and debugged with gdb v9.2 and still getting segfaults when launching with tmuxp.
