The problem seems to be that the curl app is mixing memory allocations done by
libcurl or by itself and it calls free() on both types of alloc, while it
*MUST* use curl_free() to free libcurl-allocated memory.
On unix-like systems this problem only occurs for debug-enabled builds as they
enabled libcurls memory-debug-system that wrap the allocations with debug
Can you please check if this patch cures the problem for you:
