We sometimes store .el/.elc files in gzipped form, but .gz files don't usually contain literal strings contained in the original (M-x find-file-literally seems to confirm this). We can see some of your org agenda in the backtrace, so that shouldn't be it. > (gdb) p $rsp > $10 =3D (void *) 0x7fffffff95f8 Nowhere near the corrupt data. Again, very strange. Pip
