It is designed to clear its internal state prior to returning from yyparse. However, if a parser action executes a return statement directly (this is not recommended), then the cleanup will be bypassed, which is likely to create a memory leak.

As an experimental feature, Bison can also generate IELR (1) or canonical LR (1) parser tables.
WebThis computes the thermal conductivity and specific heat of B4C. Due to the Grüneisen anharmonicity parameter ( \gamma γ) being dependent on specific heat, thermal conductivity is calculated after specific heat. The thermal conductivity also requires porosity and a capture burnup. Capture burnup, x x, is the fraction of boron atoms that have ... http://web.mit.edu/gnu/doc/html/bison_4.html
