Title:
malloc hangs when ltp mallocstress is run repeatedly
Status in “eglibc” package in Ubuntu:
New
Status in “eglibc” source package in Precise:
New
Bug description:
- malloc sleeps continously when the mallocstress application which part of ltp package is executed in a loop.
- From gdb backtrace it appears to be for a futex to be released in libc code. This is deadlock in glibc
There are some discussions going on for including this fix in next eglibc release.
