Hi All, I am getting segfault while using i2d_X509_SIG() in FIPS mode. (gdb) bt #0 0x01f95045 in __memcpy_ssse3_rep () from /lib/libc.so.6 #1 0x00466837 in asn1_ex_i2c () from /usr/local/cm/lib/libcrypto.so.1.0.1 #2 0x00466a36 in asn1_i2d_ex_primitive () from /usr/local/cm/lib/libcrypto.so.1.0.1 #3 0x00466c4c in ASN1_item_ex_i2d () from /usr/local/cm/lib/libcrypto.so.1.0.1 #4 0x0046727a in asn1_template_ex_i2d () from /usr/local/cm/lib/libcrypto.so.1.0.1 #5 0x00466eb3 in ASN1_item_ex_i2d () from /usr/local/cm/lib/libcrypto.so.1.0.1 #6 0x004675f3 in ASN1_item_i2d () from /usr/local/cm/lib/libcrypto.so.1.0.1 #7 0x0045fb3e in i2d_X509_SIG () from /usr/local/cm/lib/libcrypto.so.1.0.1 unsigned char *ptr, *tmp=NULL; len=i2d_X509_SIG(&sig,NULL); --> No issue sig.algor->algorithm=OBJ_nid2obj(NID_sha1); tmp = (unsigned char*) malloc(512+1); ptr=tmp; i2d_X509_SIG(&sig, &p); -->while calling secod time gettign core file. Its working fine in nonfips mode. But in FIPS getting core files. Please let me know how can i solve this issue.
