APER segfault about asn1c HOT 8 CLOSED

Hi @johvik,

Thanks for reporting this problem, could you also provide also xer or aper files for the example asn1 definition and all commands you need to execute to reproduce this segfault.

Do you have plans to work on a fix?

from asn1c.

Let me second this request. @johvik please provide a xer file that demonstrates the problem.

from asn1c.

Here is a sample that reproduces the issue:

#include <ChoiceExtended1.h>
#include <asn_application.h>

int
main()
{
    ChoiceExtended1_t c;
    memset(&c, 0, sizeof(c));
    c.present = ChoiceExtended1_PR_b;
    c.choice.b = Enum_one;

    uint8_t buffer[500];
    asn_encode_to_buffer(NULL,
                         ATS_ALIGNED_BASIC_PER,
                         &asn_DEF_ChoiceExtended1,
                         &c,
                         &buffer,
                         sizeof(buffer));
}

As a temporary workaround I'm using aper_put_nsnnwn from vlm#125. @velichkov I'm afraid I do not have time to make a permanent fix :/

@johvik thank you for the code example. But it would really help if you could provide XER-encoded data file for the ASN.1 that causes this APER problem.

from asn1c.

Do you mean this?

<ChoiceExtended1>
    <b><one/></b>
</ChoiceExtended1>

from asn1c.

Yes! Thank you!

from asn1c.

I have a preliminary solution, will push later.

from asn1c.

@johvik thank you - you've provided great info that both unambiguously described the bug, and pointed out a likely solution.
