If a config file contains a line with more than 255 chars then mutt will hang up with a Segmentation fault.
I'm no longer on mutt-dev but will email upstream re this.
OK .. i'm not having any luck with finding other reports of this. Could you please send more details, such as gcc, glibc, binutils version and CFLAGS machine type etc. Also an example of the string would be useful. The more details you can gie here the better to help me track this down.
The output of 'emerge info' may also be helpful :)
Excuse my delay. Here are the requested information. Nevertheless I tried another time to compile mutt and now it starts without a segfault. I remembered a suggested change in the CFLAGS from -O3 in -O2 in one of the latest system-updates. So I compiled mutt again with -O3 and the segfault appeared. -O2 works fine. Maybe it's not a mutt but a gcc-Problem with heavy optimazation that it can't read a string containing more than 255 chars at once? celeborn root # uname -a Linux celeborn.wh-og.hs-niederrhein.de 2.4.20-rc4-ben0 #6 Fre Nov 29 03:14:09 CET 2002 ppc 745/755 GNU/Linux [The kernel is independent.

Thank you for the additional info. This may be a ppc issue as i also had segfaults and had rebuilt with less aggressive CFLAGS and, as you also found, the problem disapeared. I've had no reports of this from x86/sparc etc and i think it's fairly safe to say that this is confined to ppc. I intend to adjust the .ebuild to adjust CFLAGS (based on an arch). My suspicion is that the bug appeared with a glibc update as i only noticed only noticed post glibc-2.3.1. Could you send me the output of `qpkg -I -v glibc`? Thanks again for reporting this,
Maybe you're right. The output of qpkg is sys-libs/glibc-2.3.1-r2 * And I can't remember that I ever had a version older than 2.3.x on my system.
After a lot of changes to gcc, glibc etc. I tried compiling mutt again with -O3. There is still the same error. In the attachment is an ebuild that will replace the -O[3-9] flag to -O2 for ppc-architectures. Additionally there is a patch for editing threads (Bug #12165) included.

Created attachment 9124 [details] ebuild described in comment #7
*** Bug 12165 has been marked as a duplicate of this bug. ***
Another thing for track down the fault. I found in dmesg the following lines: Process mutt tried to read below stack addr: 7575af44, gpr1: 7fffe080, pc: 0fc9c3a4, lr: 0fd60820
this looks like CFLAGS issues, lately I have noticed that mcpu=750 is _evil_. THere have been (and still are _many_ problms with this optimixation selection). In fact it is getting so bad that I am probably going to remove it from out reccomended CFLAGS permanenetly. now if people actually _updated_ their make.conf and looked at it we might have some success with that approach.
Deleted -mcpu=750 from my CFLAGS and built mutt with -O3. There's still the segfault on start.
well, since you reported this bug and are now a dev, i'll toss this one back to you hehe. I dont know any other ppc devs handy that are using mutt
Created attachment 9620 [details] ebuild without errors Alright. There's now a new ebuild without errors (as lintool says) I suggest for now to bring this ebuild into portage, in order to change -O3 to -O2. Why there's a stack "underflow" I can't tell. This seems only ppc-related.
Created attachment 9623 [details] ebuild without errors Something went wrong with the last attachment (maybe because I used lynx)
added new ebuild (for version 1.4.1 actually) to CVS
