Hi All,

I found several command that cause a "Program received signal SIGSEGV, Segmentation fault.", but it can be caused by work in progress.

(JTSDK-QT 5.5 ) C:\JTSDK\zzloc\install\Debug\bin)ft8code -t
    Message                Decoded              Err? Type

At line 1 of file C:\JTSDK\zzloc\src\lib\ft8\genft8.f90
Fortran runtime error: Actual string length is shorter than the declared one for dummy argument 'msg37' (0/37)

(JTSDK-QT 5.5 ) C:\JTSDK\zzloc\install\Debug\bin)msk144code -t
     Message                 Decoded                Err? Type

**.          * 0:
At line 39 of file C:\JTSDK\zzloc\src\lib\msk144code.f90
Fortran runtime error: Index '65537' of dimension 1 of array 'testmsg' above upper bound of 75

I try to switch to MKS144 mode, in a new enviroment (wsjtx -r ZZ)
Seem that I cannot switch to that mode without a crash.

The most strange error is gdb error.
