From Bugzilla Helper: User-Agent: Mozilla/4.76 [en] (X11; U; Linux 2.4.8 i686) Description of problem: gcc 2.96-85 reports an internal compiler error when executing the command make -f gcc.mak in order to compile the regex part of the boost C++ library 1.23.0 (www.boost.org).

Can you provide a preprocessed testcase (ie. add -save-temps and attach here cregex.ii)?
Created attachment 28353 [details] cregex.ii as requested
In the initial bug report I used STLport 4.5b8 (www.stlport.org) to compile the regex library but the Internal Compiler Error also occurs if the preinstalled GNU STL is used instead.
Should be fixed in gcc-c++-2.96-97.
*** Bug 63960 has been marked as a duplicate of this bug. ***
gcc-2.96 is too old. Its release cycle was finished long ago. Also Jakub wrote about fixing the bug in gcc-2.96-97. Therefore I am closing the case. If it is still important we could reopen it.
