Bug 656850 – net-misc/freerdp-2.0.0_rc2-r1: _aligned_free: memory block was not allocated by _aligned_malloc!

• Status: RESOLVED UPSTREAM
• Product: Gentoo Linux

[Description Theo van Rijn 2018-05-29 15:47:38 UTC]

xfreerdp crashes when I start my favorite RDP session with version freerdp-2.0.0_rc2-r1. I did not have this issue with 2.0.0_rc1-r1. The removing the option "+async-update" also fixes the issue.

Here is the start command and the begin of the error reported:

Please provide emerge --info net-misc/freerdp.

What do you mean by this? There is no USE flag called "async-update".

[Comment 2 Theo van Rijn 2018-06-01 23:46:24 UTC]

async-update is a command line parameter to xfreerd. Without that parameter set, the crash does not happen.

[Comment 3 Mike Gilbert 2018-06-02 02:43:06 UTC]

In that case, please report the issue upstream.
