* [Bug malloc/15160] New: memusagestat crashes with FPE with programs that don't use malloc @ 2013-02-19 13:47 siddhesh at redhat dot com 2013-02-19 13:48 ` [Bug malloc/15160] " siddhesh at redhat dot com ` (2 more replies) 0 siblings, 3 replies; 4+ messages in thread From: siddhesh at redhat dot com @ 2013-02-19 13:47 UTC (permalink / raw) To: glibc-bugs http://sourceware.org/bugzilla/show_bug.cgi?id=15160 Bug #: 15160 Summary: memusagestat crashes with FPE with programs that don't use malloc Product: glibc Version: unspecified Status: NEW Severity: normal Priority: P2 Component: malloc AssignedTo: siddhesh@redhat.com ReportedBy: siddhesh@redhat.com Classification: Unclassified For programs that don't use malloc, memusage generates statistics with 0 maxheap_size, which results in a divide-by-zero FPE when it tries to generate the graph image. Steps to reproduce: $ cat > foo.c #include <stdio.h> int main (int argc, char **argv) { int i; for (i = 0; i < 10000; i++) puts (argv[0]); return 0; } ^D $ gcc foo.c $ LD_PRELOAD=/glibc-build/malloc/libmemusage.so \ MEMUSAGE_OUTPUT=/tmp/memusage.TSY4YO ./a.out /glibc-build/malloc/memusagestat /tmp/memusage.TSY4YO x.png Actual Result: Floating point exception Expected Result: Graph showing 0 utilization for dynamic memory allocation and actual stack utilization. -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug. ^ permalink raw reply [flat|nested] 4+ messages in thread
