Details:

I am using "symbolic" package 2.9.0 and I have installed python 3.9 with sympy
1.5.1 (sympy 1.6.2 fails to work) on Win 10 Enterprise 1809 x64.

The commands to execute before pasting:

pkg load symbolic
setenv PYTHON python
syms alpha m_x m_y s_x s_y x y
TM = [[1 m_x 0]; [m_y 1 0]; [0 0 1]]
TO = [[1 0 x]; [0 1 y]; [0 0 1]]
TS = [[s_x 0 0]; [0 s_y 0]; [0 0 1]]
TR = [[cos(alpha) -sin(alpha) 0]; [sin(alpha) cos(alpha) 0]; [0 0 1]]

The commands to paste (all 64 lines at once):
T_M=TM
T_MO=TO*TM
T_MOR=TR*TO*TM
T_MORS=TS*TR*TO*TM
T_MOS=TS*TO*TM
T_MOSR=TR*TS*TO*TM
T_MR=TR*TM
T_MRO=TO*TR*TM
T_MROS=TS*TO*TR*TM
T_MRS=TS*TR*TM
T_MRSO=TO*TS*TR*TM
T_MS=TS*TM
T_MSO=TO*TS*TM
T_MSOR=TR*TO*TS*TM
T_MSR=TR*TS*TM
T_MSRO=TO*TR*TS*TM
T_O=TO
T_OM=TM*TO
T_OMR=TR*TM*TO
T_OMRS=TS*TR*TM*TO
T_OMS=TS*TM*TO
T_OMSR=TR*TS*TM*TO
T_OR=TR*TO
T_ORM=TM*TR*TO
T_ORMS=TS*TM*TR*TO
T_ORS=TS*TR*TO
T_ORSM=TM*TS*TR*TO
T_OS=TS*TO
T_OSM=TM*TS*TO
T_OSMR=TR*TM*TS*TO
T_OSR=TR*TS*TO
T_OSRM=TM*TR*TS*TO
T_R=TR
T_RM=TM*TR
T_RMO=TO*TM*TR
T_RMOS=TS*TO*TM*TR
T_RMS=TS*TM*TR
T_RMSO=TO*TS*TM*TR
T_RO=TO*TR
T_ROM=TM*TO*TR
T_ROMS=TS*TM*TO*TR
T_ROS=TS*TO*TR
T_ROSM=TM*TS*TO*TR
T_RS=TS*TR
T_RSM=TM*TS*TR
T_RSMO=TO*TM*TS*TR
T_RSO=TO*TS*TR
T_RSOM=TM*TO*TS*TR
T_S=TS
T_SM=TM*TS
T_SMO=TO*TM*TS
T_SMOR=TR*TO*TM*TS
T_SMR=TR*TM*TS
T_SMRO=TO*TR*TM*TS
T_SO=TO*TS
T_SOM=TM*TO*TS
T_SOMR=TR*TM*TO*TS
T_SOR=TR*TO*TS
T_SORM=TM*TR*TO*TS
T_SR=TR*TS
T_SRM=TM*TR*TS
T_SRMO=TO*TM*TR*TS
T_SRO=TO*TR*TS
T_SROM=TM*TO*TR*TS

It crashes somewhere between T_RO and T_RS: Octave just quits without notice.
