Holger Vogt 3930e27501 New compatibility modes (set ngbehavior=??): PS LT LTPS PSA LTA LTPSA 
PS: PSPICE comp. in .include files., LT: LTSPICE comp. in .include files.
LTPS: both, PSA: PSPICE comp. in complete input deck,
LTA and LTPSA: comp. in complete input deck for LT or both.

Add functions uplim, dnlim, uplim_tanh, dnlim_tanh.

Holger Vogt d636f7899b cp_enqvar() returns freshly malloced variables as well 
as variables owned by somebody else, e.g. from ft_curckt->ci_vars.
The new function parameter tbfreed notifies the caller if the
variable is malloced here and may be freed safely.

No diode capacitance

Holger Vogt ae89381bb6 Prevent a segfault if multiple circuits are freed upon 'quit' 
by checking if a 'recent_deck' that is to be freed also exists
with same address in ci_mcdeck of another circuit. If yes, set
this to NULL before freeing.
 2018-09-26 18:47:20 +02:00
Holger Vogt a17de08b5c free only value that have been TMALLOCed or TREALLOCed 2018-09-26 18:47:06 +02:00
Holger Vogt 2a3c88add6 Commit ad0f59657 ("fix a memory leak", 2018-08-13) made 
the special device parameter notation @m1[vt0] unusable.
This fix frees only the tokens that are already overridden
in function INPinsertNofree(). The reason for using this
function instead of INPinsert() is not obvious.
 2018-09-26 18:46:12 +02:00
Holger Vogt 5f0b2f344e spurious crash: MIFgettok deliveres strings that cannot be freed: 
MS Windows, VS or MSYS2/MINGW/GCC, shared ngspice, single character
token at end of line, compiled with optimization, not in debug mode.
Preliminary fix: TMALLOC another byte to token.
Origin of bug still unknown: Source code error? MS library error?
Re-write of MIFgettok does not show this error (so far...).
