Re: [Help-glpk] glp_main frees environment

[glpk xypron]

Hello Nigel,

you assign memory to lp, but you do not release it before calling
glpk_main.

glp_main calls glp_free_env in line 1321 of glpk-4.47/src/glpapi21.c
glp_free_env checks if all blocks are released.

It might be preferable to move glp_free_env to glpsol.c

Please, remember glp_main is not a documented API function in glpk.pdf.

Best regards

Xypron
