I believe those problems are related to the recent check-ins. For example, consider the following code tc.C. When run interactively, typing ^D on the keyboars has no effect, the program does not finish. When the input and output file descriptors are redirected to files, the programm does not terminate either. There are other io related problems I have not yet investigated. For example, when running the boost regression suite, the output of the html status file, cs-linux.html, is truncated. "libs/config/test/config_info.cpp run" is the last line (the first test of the regression suite), though all tests pass. >How-To-Repeat: source code tc.C #include <iostream> int main () { std::cout << std::cin.rdbuf(); } g++ -v -o tc tc.C -W -Wall Reading specs from /usr/local/lib/gcc-lib/i686-pc-linux-gnu/3.1.1/specs Configured with: ../gcc/configure --enable-shared --disable-nls --enable-threads=posix --enable-languages=c,c++,f77,objc Thread model: posix gcc version 3.1.1 20020519 (prerelease) /usr/local/lib/gcc-lib/i686-pc-linux-gnu/3.1.1/cc1plus -v -D__GNUC__=3 -D__GNUC_MINOR__=1 -D__GNUC_PATCHLEVEL__=1 -D__ELF__ -Dunix -D__gnu_linux__ -Dlinux -D__ELF__ -D__unix__ -D__gnu_linux__ -D__linux__ -D__unix -D__linux -Asystem=posix -D__NO_INLINE__ -D__STDC_HOSTED__=1 -D_GNU_SOURCE -Acpu=i386 -Amachine=i386 -Di386 -D__i386 -D__i386__ -D__tune_i686__ -D__tune_pentiumpro__ tc.C -D__GNUG__=3 -D__DEPRECATED -D__EXCEPTIONS -D__GXX_ABI_VERSION=100 -quiet -dumpbase tc.C -W -Wall -version -o /tmp/ccPq221W.s GNU CPP version 3.1.1 20020519 (prerelease) (cpplib) (i386 Linux/ELF) GNU C++ version 3.1.1 20020519 (prerelease) (i686-pc-linux-gnu) compiled by GNU C version 3.1.1 20020519 (prerelease). ignoring nonexistent directory "NONE/include" ignoring nonexistent directory "/usr/local/i686-pc-linux-gnu/include" #include "..." search starts here: #include <...> search starts here: /usr/local/include/g++-v3 /usr/local/include/g++-v3/i686-pc-linux-gnu /usr/local/include/g++-v3/backward /usr/local/include /usr/local/lib/gcc-lib/i686-pc-linux-gnu/3.1.1/include /usr/include End of search list. /usr/local/lib/gcc-lib/i686-pc-linux-gnu/3.1.1/../../../../i686-pc-linux-gnu/bin/as -V -Qy -o /tmp/ccd2RdDf.o /tmp/ccPq221W.s GNU assembler version 020428 (i686-pc-linux-gnu) using BFD version 020428 20020428 /usr/local/lib/gcc-lib/i686-pc-linux-gnu/3.1.1/collect2 --eh-frame-hdr -m elf_i386 -dynamic-linker /lib/ld-linux.so.2 -o tc /usr/lib/crt1.o /usr/lib/crti.o /usr/local/lib/gcc-lib/i686-pc-linux-gnu/3.1.1/crtbegin.o -L/usr/local/lib/gcc-lib/i686-pc-linux-gnu/3.1.1 -L/usr/local/lib/gcc-lib/i686-pc-linux-gnu/3.1.1/../../../../i686-pc-linux-gnu/lib -L/usr/local/lib/gcc-lib/i686-pc-linux-gnu/3.1.1/../../.. /tmp/ccd2RdDf.o -lstdc++ -lm -lgcc_s -lgcc -lc -lgcc_s -lgcc /usr/local/lib/gcc-lib/i686-pc-linux-gnu/3.1.1/crtend.o /usr/lib/crtn.o ./tc < tc.C > aus // does not finish ./tc hallo ^D^D^D^D^D^D^D //does not return to shell either! >Fix: >Release-Note: >Audit-Trail: >Unformatted:
