Hi,
I met a curl_resolv_timeout crash in AIX7.1 when curl is
running in multi-thread. Curl version is the latest, 7.45.0. The call stack is:
Segmentation fault in addbyter at 0x8000000004b3418 ($t3)
0x8000000004b3418 (addbyter+0x18) 98650000 stb r3,0x0(r5)
(dbx) where
addbyter(??, ??) at 0x8000000004b3418
dprintf_formatf(??, ??, ??, ??) at 0x8000000004b3564
curl_mvsnprintf(??, ??, ??, ??) at 0x8000000004b3324
Curl_failf(0x90000000002ab90, 0x8001000a008ef68, 0x44204080,
0x800000000000d032, 0x3ffc000000000003, 0x2ba8, 0x0, 0x0) at 0x8000000004b31d0
Curl_resolv_timeout(??, ??, ??, ??, ??) at 0x8000000004bdd58
And I have already set the CURLOPT_NOSIGNAL to 1L according to advice.
But in redhat linux, my program runs OK, the core dump only happens in AIX7.1.
And I also add the configure option --enable-threaded-resolver to compile curl,
the core dump still happens.
Could someone give me some advice ?
Thanks a lot.
B.R.
Fred
