From Bugzilla Helper: User-Agent: Mozilla/4.76 [en] (X11; U; Linux 2.2.14-5.0 i586) i have been trying to compile the openh323 source code for a few days now. eventually, after working through all sorts of memory problems, i have finally managed to get gcc to crash the way i saw it crash once. i was just doing a normal compile, and i get the crash output listed in the 'actual results' area. Reproducible: Always Steps to Reproduce: 1. get pwlib_min_1.1pl19.tar.gz & openh323_1.1pl1.tar.gz from http://openh323.org/bin/ 2. untar in your home directory ( required for some reason ) then execute the following commands: 3. cd ~/pwlib/ 4. make both 5. cd ~/openh323/ 6. make opt i get the crash when it is compiling h245_3.cxx this is the fourth or fifth file though, and two of the prior ones take a _very_ long time to compile ( > 9 hours on my p-100 w/ 64MB RAM ). Actual Results: /usr/include/g++-3/iomanip.h: In method `void H245_H223AL1MParameters::PrintOn (ostream &) const': /usr/include/g++-3/iomanip.h:56: Internal error: Segmentation fault.

Can you please rerun the g++ command line on h245_3.cxx with the options which result in the segfault with additional -save-temps -v options and attach here h245_3.ii it creates (and mention the actual g++ command line used)?
Created attachment 16685 [details] gcc crashed with internal error
I got a gcc crash when compiling a file (I compiled again with --save-temps and have attached it to this bug report). Note: the program compiles fine under the CVS g++-3.0 branch and is okay under g++-2.95. So, two possibilities: 1. A problem in gcc that was fixed between 2.96 and 3.0 2. A kernel/swap problem in RedHat 7.1 lakshman
I did some testing. I found that gcc would crash on the same non-comment line of the file __regardless of which line it was___ i.e. I commented out a block of code just before the point gcc crashed with " #if 0 ... #endif " and sure enough, gcc crashed immediately after the #endif. Somehow, gcc can not handle the size of the file maybe? The RedHat 7.1 machine I am building on has only 64MB memory. lakshman
No, the issue is related to old-style ABI mangling of DimVal < 0 - so, 0 - mo, -1 - to, 0 - co > (particularly -1 - to). It does not happen on gcc-3.0 branch because it uses completely different mangling, and does not happen in 2.95.x because the bug was introduced during development after 2.95.x was branched off. I made a patch which seems to work, will include it in gcc-c++-2.96-83.
Hi all, I've update the gcc to 2.96.85 following the instruction in redhat support, But I still encounter the segmentation fault while compiling mysql, can anyone tell me how to fix it? It can be compiled in redhat7.0 without error...
