Dear Sir/Madam,
We have been using libcurl.dll for a few years to do almost all our
HTTP/HTTPS requests in our OpenEdge 11.7 environment (= our custom ERP
solution).
For more info about OpenEdge 11.7 see :
https://www.progress.com/openedge/whats-new-11-7.
When libcurl.dll 7.84.0 or higher is used in an OpenEdge 11.7 session, then
the OpenEdge session crashes when the libcurl.dll is released from memory.
A .protrace file is generated with the following error :
*Exception code: C0000005 ACCESS_VIOLATION*
With the following small test OpenEdge program (test_libcurl.p) we are able
to reproduce the issue :
/* *************************** Definitions ************************** */
block-level on error undo, throw.
/* ******************** Preprocessor Definitions ******************** */
procedure curl_global_init external "libcurl.dll" cdecl:
define input parameter i-init as long.
define return parameter p-Return as long.
end procedure.
procedure curl_global_cleanup external "libcurl.dll" cdecl:
end procedure.
/* *************************** Main Block *************************** */
log-manager:logfile-name = "C:\OpenEdge\WRK117\test_libcurl.log".
&GLOBAL-DEFINE CURL_GLOBAL_NOTHING 0
&GLOBAL-DEFINE CURL_GLOBAL_SSL 1
&GLOBAL-DEFINE CURL_GLOBAL_WIN32 2
&GLOBAL-DEFINE CURL_GLOBAL_ALL ({&CURL_GLOBAL_SSL} +
{&CURL_GLOBAL_WIN32})
&GLOBAL-DEFINE CURLE_OK 0
define variable iReturn as integer no-undo.
define variable iCurlHandle as integer no-undo.
run *curl_global_init*(input {&CURL_GLOBAL_ALL}, output iReturn).
log-manager:write-message(substitute("curl_global_init returned &1.",
iReturn)).
run *curl_global_cleanup*.
log-manager:close-log().
We experience no issues with libcurl.dll 7.83.1 and lower.
Any idea how we can solve the above issue ?
King regards,
Patrick
