Hi,

I am trying to run CurlAgent process, which is using libcurl5.2.0 on Wind River Linux.
When this process calls curl_easy_init function to do the curl initialization, I am getting illegal instruction issue which is as follows.

[ 6451.875789] grsec: From 192.168.100.103: Illegal instruction occurred at aa65e32b in /usr/games/MQTT/branch_TGateOne_IDF14/xmpp_if/CurlAgent/CurlAgent[CurlAgent:8132] uid/euid:0/0 gid/egid:0/0, parent /bin/bash[sh:7975] uid/euid:0/0 gid/egid:0/0
[ 6451.909066] grsec: From 192.168.100.103: denied resource overstep by requesting 4096 for RLIMIT_CORE against limit 0 for /usr/games/MQTT/branch_TGateOne_IDF14/xmpp_if/CurlAgent/CurlAgent[CurlAgent:8132] uid/euid:0/0 gid/egid:0/0, parent /bin/bash[sh:7975] uid/euid:0/0 gid/egid:0/0

Does someone is having any pointers to look into this issue?

Regards
Mohita

IMO an "Illegal instruction" could be related rather to compiler flag issue than grSecurity. Did you compiled the exe it on a different machine/processor than where you run it now ?

Post your `emerge --info curl`, please.
