[ERROR STA-0026] unterminated string constant #2063
Description
Description
There is a buffer overflow in read_liberty -corner Typical /home/philipp/libresilicon/StdCellLib/Catalog/gf180_stdcelllib_1/dependencies/pdks/gf180mcuD/libs.ref/gf180mcu_fd_sc_mcu7t5v0/liberty/gf180mcu_fd_sc_mcu7t5v0__tt_025C_5v00.lib
when reading liberty files with a function definition that is 67797 characters long. The string is properly terminated, but most likely due to the too small buffer, it thinks that the string constant isn't terminated.
Expected Behavior
Well, 67790 characters is long, but it would be nice to have the scalability to even such very complex cells. I will also try to produce a more compact function description, but finding the right algorithms for that will take some time.
