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 ?
