Category: libcurl
Group: crash
Status: Open
Resolution: None
Priority: 5
Private: No
Submitted By: olivier cloarec (cloarec)
Assigned to: Daniel Stenberg (bagder)
Summary: Segmentation fault with Redhat 5.2

Initial Comment:
- CURL version: 7.19.2 (same problem with version 7.13)

- OS: Redhat 5.2 (with Redhat 4, it was OK)

- Compiled with following commands (cross compiler used):
autoconf;./configure --with-random=/dev/urandom --without-libidn --without-ssl --host=i386-angie-linux-gnu;make

- Used library: libcurl.a

- Problem: Program receives a SIGSEGV signal caused by libcurl.

- Workaround:
In hostip.c, I replaced "#define USE_ALARM_TIMEOUT" with "#undef USE_ALARM_TIMEOUT".
The library doesn't crash anymore but I don't really know the potential consequences of this modification.

You will find here under the backtrace.

Regards,

Olivier.
