Thank you we appreciate your help.

In my testing it appeared that frame->session was released but I was not able to prove that conclusively and I didn't have the time to check where it was released. You can credit the Alpine Linux team for helping out.

I was able to resolve all the bugs with the attached patch file. Can you review and apply them if you agree? It contains the following adjustments. iaxmodem.c: initialize tioflags before using lib/libiax2/src/iax.c: remove a check on a structure that was already free'd lib/spandsp/src/at_interpreter.c: apply a patch that was provided in a later version of this library Thank you, Bob

We are using Hylafaxplus 7.0.3 to receive faxes from iaxmodem. The faxgetty program receives the fax, calls the faxrcvd script and then iaxmodem crashes. We put a pause in faxrcvd so that it would take no actions and iaxmodem still crashes. The malloc () function was recently updated on Alpine 3.13 so it is possible that it has a problem or that it is more sensitive to errors in the existing code. We would appreciate any suggestions you may have on how to track down this error.

We are using iaxmodem 1.3.2 on Alpine Linux 3.13 and it is crashing when using Hylafaxplus 7.0.3. The problem seems to be triggered by an access to freed memory. I attached the valgrind log file which includes debugging data to identify the source of the problem. Can you assist us in finding in the root cause? Thank you, Bob
