Description (last modified by andrew_b) (diff)

mc crashes on Solaris 11.1 right after start. I've just built it, I've even had one successful session with it, but now it crashes. May be this has something to do with the fact that I changed the prompt.

OS: Solaris 11.1
GCC: 4.5.2
Comiler flags: -g -m64
Configure arguments: --prefix=/usr/local/mc --disable-dtrace
Shell: bash

Change History

comment:1 Changed 11 years ago by andrew_b

​In POSIX.1-2001:

A third case is when inbuf is NULL or *inbuf is NULL, and outbuf is NULL or *outbuf is NULL. In this case, the iconv() function sets cd's conversion state to the initial state.

​In Solaris:

For state-dependent encodings, the conversion descriptor cd is placed into its initial shift state by a call for which inbuf is a null pointer, or for which inbuf points to a null pointer. When iconv() is called in this way, and if outbuf is not a null pointer or a pointer to a null pointer, and outbytesleft points to a positive value, iconv() will place, into the output buffer, the byte sequence to change the output buffer to its initial shift state.

It looks like iconv (NULL, NULL, NULL, NULL) isn't supported in Solaris 11.1, i. e. outbuf shouldn't be NULL.

Looks like this change is triggered by some SRU, because I have mc working on a non-patched 11.1. Target machine with crashing mc is SRU 17.5. Anyway on Solaris 11.2 this will be incorporated in the point-release, triggering this change on all newly-installed instances.

comment:5 Changed 11 years ago by slavazanko

I found some tips about Solaris and iconv stuff:
​https://developer.gnome.org/glib/2.37/glib-building.html

Just search by 'GLib depends on a number of other libraries' text on the page and check all iconv-related dependencies.

I don't know will it be helpful for you or not, but in any way we don't have ability to reproduce the bug. I hope that the bug is related to libraries environment, not to implementation of iconv-stuff in mc.

comment:6 Changed 11 years ago by drookie

Thanks for noticing, I've rebuilt local glib with local GNU libiconv and mc started to work.
But, anyway, on older Solaris versions this was working even with system iconv(). And I still think that getting with to work with local iconv() is the idea.

Anyway, thanks for your work.
