Confirmed that this is also in 1_16_0_6. Program crashes with error:

- - glibc detected *** bin/do-not-directly-run-secondlife-bin: double free or corruption (out): 0x0cb68558 ***

I can't reproduce the crush. Can you report more details on your environment?

My test environment is as follows:
Athlon64 3800+, GeForce 6800, Fedora 7, SCIM-Anthy.
With environment variables: LANG=ja_JP.UTF-8, GK_IM_MODULE=xim, and XMODIFIERS=@im=SCIM
Tested with Viewer 1.18.0.6.

This issue seems to be caused by SDL's and/or GTK's handling of input method.

See discussion on ~~VWR-240~~.

Confirmed on 1_18_1_2

setting GTK_IM_MODULE=xim solves it.

environnment:
Ubuntu Feisty 7.04 with SCIM
Intel Centrino Mobile architecture
ATI Radeon 9000 Mobile
LANG=en_US.UTF-8
GTK_IM_MODULE=scim
XMODIFIERS=@im=SCIM

I wonder how common this problem is. Does anyone see any disadvantages to making:
GTK_IM_MODULE=xim
the default as a workaround?

(or at least only if GTK_IM_MODULE is already scim)

Attached proposed simple workaround patch.

Problem still exists as of 1.18.1.2, took me an HOUR to find the cause. Any reason why such a simple workaround hasn't yet been included?

Arigatou.

Fixed internally, thanks for the feedback.

(FYI - the committed fix was the workaround I attached.)

I'm slightly unconfortable with the attached patch. It looks like a half measure.

I would prefer either

(a) always set GTK_IM_MODULE to "xim" (because any other settings doesn't work with SDL anyway)

(b) keep the "if" as is and set XMODIFIERS="@im=SCIM", too (since we know that the user wants to use SCIM in the case.)
