Sukchan Lee acetcom at gmail.comIt seems that this is not a problem with the asn1c library. There is a bug in ogs_calloc()/ogs_free(). I've changed memory alloc()/free() as below. https://github.com/open5gs/nextepc/commit/dba1fcac5c29509a9e662a9fedc37a674a416df3 And then, the source code is modified like the following. diff --git a/lib/asn1c/common/asn_internal.h b/lib/asn1c/common/asn_internal.h index 77e005f7..d561043b 100644 --- a/lib/asn1c/common/asn_internal.h +++ b/lib/asn1c/common/asn_internal.h @@ -23,7 +23,7 @@ extern "C" { #define ASN1C_ENVIRONMENT_VERSION 923 /* Compile-time version */ int get_asn1c_environment_version(void); /* Run-time version */ -#if 0 /* modified by acetcom */ +#if 1 /* modified by acetcom */ #define CALLOC(nmemb, size) calloc(nmemb, size) #define MALLOC(size) malloc(size) #define REALLOC(oldptr, size) realloc(oldptr, size) So, s1ap encoder/decoder is executed with system's calloc()/free(). And then, run the following command. $ ./test/testcsfb crash-test The above test is not crashed. Of course, if ogs_calloc()/ogs_free() is used, the above test command is crashed. So, I need to analyze what the bug of ogs-memory.c raise this crash. Thanks! On Mon, Jul 22, 2019 at 12:02 AM Sukchan Lee <acetcom at gmail.com> wrote: > Hi Harald, > > Of course, I will.
