lorenzo 66797fdebc Fixes a memory corruption bug resulting from improper parsing 
and accessing of array parameters in OSDI models
 2026-02-03 14:17:59 +01:00
Holger Vogt af28d2416d free(info.errors) leads to a assertion error on the heap. 
On Windows it reads:

is_block_type_valid(header->_block_use).

Memory for info.errors is allocated in the osdi device dll
during the call to

      descr->setup_instance((void *)&handle, inst, model, temp,
                            connected_terminals, sim_params, &init_info);

(in fcn OSDIsetup(), line 254 of osdisetup.c).
Therefore ngspice is not the owner of this memory and thus cannot free it.

Fixes bug no. 803.

Holger Vogt 5d207f7b43 Add environmental variable NGSPICE_OSDI_DIR. It may contain 
a path for *.osdi files (compiled Verilog-A models). The search
sequence for a *.osdi file now is:
Absolute path (if any)
Linux home directory ~/
Path in NGSPICE_OSDI_DIR
Path of netlist loaded
Path of executable ngspice.exe
Path of 'Current working directory'

Holger Vogt 26cf1a7a57 max_align_t is used to examine the largest alignment requirement, 
and it is expected to check the alignment value via alignof, not sizeof.

Otherwise, __attribute__((aligned)) can complain as required alignment
being invalid, e.g. on s390x.
