--- Begin Message ---Package: ltrace Version: 0.7.3+git20240814-0.3 Severity: normal Tags: upstream X-Debbugs-Cc: ri...@google.com Dear Maintainer, *** Reporter, please consider answering these questions, where appropriate *** * What led up to the situation? emacs was hung with 100% CPU utilisation. I wanted to know why. * What exactly did you do (or not do) that was effective (or ineffective)? I attempted to diagnose the problem using "ltrace -p". * What was the outcome of this action? ltrace crashed because one of the libraries that emacs linked against wasn't present in the filesystem, probably because it had been upgraded. * What outcome did you expect instead? ltrace shows me what emacs is doing (or nothing if emacs is just spinning inside its own code). I wrote this shell script to reproduce the issue """ #!/bin/sh -e cd `mktemp -d` echo "===> Building in $PWD ..." cat <<__END__ > lib.h void DoNothing(); __END__ cat <<__END__ > lib.c #include "lib.h" void DoNothing() {} __END__ gcc -shared -O -o liblib.so -Wall -Werror -fPIC lib.c cat <<__END__ > main.c #include <stdio.h> #include <stdlib.h> #include <unistd.h> #include "lib.h" int main() { if (unlink("liblib.so") == -1) { perror("unlink liblib.so"); exit(1); } while (1) { sleep(1); DoNothing(); } return 0; } __END__ gcc -L$PWD -Wl,-rpath=$PWD -Wall -Werror -O -o bin main.c -llib ./bin & echo "===> Running ltrace -p $! ..." ltrace -p $!
