Segfault on copy/cut/paste #144

Closed alexdrean closed 4 years ago

alexdrean commented 4 years ago

Copy/cut/pasting around seems to create glitches (calculations don't run anymore) and segfault. I can reproduce this on every system I can get my hands on.

To reproduce: Type in a few lines. Copy and paste, delete everything, paste again a few times... Very quickly glitches happen and segfault happen.

Segv analysis seems to point at some strcmp accessing 0x0...090 which is not readable. Seems like a pointer glitch (I know, that's not very useful).

Investigating a little further, it seems like this is only triggered by CUT/Paste

GDB output

Thread 1 "nasc" received signal SIGSEGV, Segmentation fault.

Could be fixed but not entirely sure.

Did some testing with C&P and this seems to be fixed. If not plz reopen.
